Moving PhpBB Hosts

We are currently running a phpBB forum on Dreamhost shared hosting and have been getting a lot of Internal Server Errors, so it's time to move to a new host.

We generally have around 200-300 members online (within the last 30 mins). We are using around 2.8TB/month of bandwidth currently. We get around 135,000 visits per month and 470,000 pageviews.

Dreamhost use their own way of measuring database usage..

Quote:

We've developed a unit of measure that helps to track database performance that we call the "conuery":
(25 * connections) + queries = Your database's conuery usage

Our database disk usage us 24mb, we are averaging around 100,000 database connections per day, around 85,000 queries per day and our "Conuery" is around 3 MCn per day (this means nothing to me either lol).

I have found a VPS package with directspace - 2x Intel Quad Core Xeon, 50GB Storage, 2Gb RAM, 2.5GB Burst Ram and 5TB of monthly bandwidth, for $35/month.

Is this likely to be an adequate solution for our needs? We would be running both the database and web services for phpBB from this box.

Also, can anyone give any hints on the best (and most seamless way) to migrate? I'm thinking that we'll get the new host to install all the services and get the box up and running, then I can ftp the files to the new server and export/import the databases. Then perform a (301?) redirect on the old host, pointing to the new IP address until the DNS is updated.

I realise that I'll need to update the config.php for phpbb with the new database details etc, along with the database details for our wordpress implementation and update the server details in the board configuration.
