Moving Servers: No E-mail Loss
May 30, 2007
I am moving a couple clients over to my server tonight, but I wanted to make sure I took steps that they don't miss any e-mail that might be sent. It is my understanding that say the switch happens tonight at midnight. Any e-mails they did not download from the old server will be stuck on there correct? Because they would come in the next morning and hit outlook and download just from the new server?
Is there a set protocol for doing this move with minimal client hic-ups?

how to go about switching mail servers.
mail.domain.com is used as the MX record and is where users point their mail clients for POP/IMAP access. I'm obviously going to be relocating the record to a new IP.
My questions are:
In the interim period, can I have exim 'redirect' POP/IMAP connections to the new IP (for users), and can I have exim relay/forward (not sure on the term in this case) mail received from old DNS caches to the new mailserver IP?

Im about to move servers as my old one was running so slow, but im worried about losing important emails in the change over. I remember reading something ages ago that said if you change a specific setting on the old server 24 hours before switching then when you switch the DNS will route to the new server quicker.
way, AVOID Stiletto Media web hosting. There support is useless and they have regular downtime, like 8-24 hours a WEEK. The servers are also incredibly slow. Dreamweaver constantly times out when trying to connect!)

I want to move around 20Gb of files from dreamhost hosting account with custom control panel to a cpanel VPS in another datacenter.
Is there anyway of transferring all the files to new host without downloading and uploading to the new host. Coz i have normal DSL and 20 GB downloading and uploading can take years.
There are some forum files CHMOD to specific values if you can transfer them without resetting them in new host also cool.
Can anyone give help? both servers have SSH and FTP
I get to know you can rar them and Wget it from the VPS.
But thats file by file.
Is there a way to move complete directory with wget command?

I have web site on one shared hosting. Now I want to move to another provider. However on first one I have around 500MB of emails which I would like to move also, because I only use web mail.
I found some instructions that I can copy Qmail's folders and emails and then restore them, but since this is something that providers will charge me for ($80 just for backup), I'm looking for another solution.
I was thinking that since both servers allow IMAP access, I could simply log in in one and another and then copy emails between folders.
- Would this work?
- When I log in with Microsoft Outlook, I only see "Inbox". I don't see "Sent" or other folders which I also have to copy. How to work around this?

Long story short, my web host is unreliable and after a down period of 3 days - I want to move my website to a new dedicated server.
Old Server - Fedora Core 6 with Plesk 8.1 (64 bit)
New Server - Cent OS 5 with Plesk 8.0 (Still to confirm version)
My problem is how to transfer all data from one server to the other? The most important item to backup are the emails, and the rest I can do manually. Ideally I would want to backup the entire server in a one, and upload it to the new one but I doubt that will be possible.

I'm going to start moving all my resellers from one dedicated server to another.
I'm going to do it like this:
Suspend their account in whm, but instead of it saying account suspended, it will be changed to something such as "Account Transfer in Progress". This will prevent changes to db's, files etc which could be lost during the transfer.
Once all accounts have been transferred I will change nameserver IP's to new server. They can then use their accounts as normal on new server.
What I want to know is:
What will happen to emails that are sent while the accounts are suspended, will they bounce?
how I could transfer the accounts (150-200) with minimal downtime, I would be interested.

Does anyone have any suggestions on how you would physically move servers from one datacenter to another with minimal downtime?
The IP address is going to change, so the server will go off and then come back online with a new ip.
Just how much downtime is acceptable before customers get annoyed?
When is the best time to do it?
Move them yourself or courier or any other ways?

I currently have 2 DNS Servers with CPanel-DNSOnly Installed, used with CPanel's DNS Clustering options to store dns entries from CPanel web servers.
I am looking to buy a Windows server(probably with plesk), which i think will not support current CPanel DNSOnly Servers ?
What i need to do is
1. Migrate CPanelDNSOnly(which uses BIND) to TinyDNS on both servers
2. with a simple web-based management of dns entries(to give control to my clients, like DomainDNS.com)
3. and auto updating of DNS Entires from other CPanel and Windows servers, without conflicting same domain records from different servers (which i think can be solved by updating entires by Latest Modified date/time).
I am not an expert, and not really sure if i will be able to setup everything myself. here i need your help, guidence, and links to tutorials and help... From where should I start? What and How should I do? Should I consider hiring a System admin? any sugestions or reference for such admins?

I have a question regarding status pages. Whilst setting up a new website, upgrading forum scripts etc what is the best way to redirect users?
I would like myself and one other person to have access to run the tasks, however I would like to redirect visitors to the website to a standby page whilst we are doing this.
What is the best method? .htaccess? IP based?

We recently moved all our hosting accounts from our servers to new servers with a new host. In the process of this move, after moving all the domains and setting the nameserver ips to the new ips, none of the sites are pulling up. I changed the ip for all nameservers to the ones provided to me by the new host but we cannot figure out why the sites are not pulling up, he says everything on his end is fine? Talking about 100+ clients who have been down for over a day now after changing the nameservers and cannot figure out whats going on. All we did was set the ips on my current nameservers to the new ips below.
Now they are claiming they can bring the sites up, but none of the clients I have talked to can bring them up. Also I cannot bring up any domains or ping them from my home or work.
Example domains that are not working that were moved:
bluetongueskinks.net
pokemongamesnow.com
The 204.16.247.150/~username works fine.
See 204.16.247.150/~pokemon
The accounts transferred over fine in WHM. We were using a dns redirect in WHM on the old server before changing nameservers to make sure it pulled them all up fine.
ips for the nameservers 204.16.247.150 and 204.16.244.150.

We have a business website that is currently hosted on Windows. There is one of those generic control panels and we are now moving to Linux hosting also with a generic control panel.
All the staff has email and large email boxes. How can we move the mail from the old Windows host to the new Linux host. Both setups have dedicated IP's and yes they are on SHARED HOSTING so the tricks to change the email would be limited.

I want to migrate a customer from his current host to a new one. The website is the easy part, site migrations are not a problem for me.
The hard part is the email. I can re-create the account, but what about the messages stored in the old server? How do I move them? How do I get all the stuff and copy it into a shared account controlled by CPanel? I think the other server uses Plesk, which uses to be a pain in the ***.

I'm in the process of moving some websites between hosts... from Dreamhost to a VPS.
Basically I want to make sure that no emails get lost in the transfer, as it's possible some people haven't collected their emails. I'm only talking about 5 or 6 sites here with about 15 mailboxes in total.
I have pop3 set up on the VPS with exim4 and courier using Maildir's. I have imap/pop3 access to emails on dreamhost and all my clients only use pop3.
Dreamhost doesn't provide direct access to the Maildir's of users, so I was planning on using offlineimap to save a copy of each mailbox and move it into the Maildir of the user on the VPS. I.e. move the contents of INBOX/new into user/Maildir/new etc. I'll do this once the dns settings have propogated so I can be sure to have every single email.
Does this sound reasonable? Is anything likely to break? Will any email clients break with any of these transferred emails? I tried it with a test account and it seemed OK, but I would like an experts opinion on whether or not this is the best way of achieving what I'm trying to do

What is the best way to handle prevent data loss in the event a hard drive goes bad in a server. We have never had one go yet but I can only imagine what a server load of domains suddenly losing their databases or sites. (giving that they didn't back their stuff up).
I know one was is a RAID setup. I just wanted to hear more.
What about if you need to move everyone from one server to another due to major upgrades? Like adding more hdd space.

i have two servers with whm/cpanel and centos,
i host my domain.com on server-A and create a account with subdomain sub.domain.com on server-A,
some days later,
i move the account website to server-B,
a> i change the domain of sub.domain.com to sub2.domain.com on server-A from whm,
b> and i edit the dns from whm and add a a address record to point to the server-B.
i think my setting is right and the link will run well,
but i am not sure why sometimes people can not link the sub.domain.com,
and they check do the check "ping sub.domain.com",
and they will get the ip of original server-A,
because it assail me for months and i'm not sure how to fix it completely.

I have a dedicated windows 2003 server at a colocation facility that i use for game server hosting. Over the past 7 months, packet loss has become horrible with random periods of massive lag. My host says it's something on my end. I use a firewall with SPI enabled. Could that be causing it?
Strange thing is, the first few months my server was at that colo, they only had around 40 other servers on a single OC-192 pipe and i never had packet loss despite having the same SPI firewall. But now they have over 300 servers on the same OC-192 pipe. Could the packet loss be caused by my SPI firewall or them overloading the network with servers?

Basically I registered with a new host. They sent me the details with obviously includes the IP address. I tested the IP address on just-ping.com and it came back with all of them having between 80% to 100% packet loss. Surely this is not normal is it? I havent moved my domain yet but it doesnt look good does it? Should I cancel?
