Hi

We're having a lot of issues with a couple of our psql servers and are going to upgrade.

Current:  Windows 2003 standard x86, v9.x psql

New:  Windows 2008 standard x64, v11.x psql

Both environments are virtual on vmware ESXi 5.1.  My plan for migration is to shut down the old servers, detach the data drive, and attach it to the new server.

My question is:  Can the new psql just attach this database as is or would it be a better plan to attach the old data drive and a same size new data drive and do some kind of import activity?

Thanks!

Tony

The PSQL environment uses the data files only, and won't care if you just move the data volume to the new server.

However, you may wish to research performance issues due to "disk alignment" problems. Your older volumes from Server 2003 are likely misaligned, and this can slow things down, further hurting performance. For best results, I'd recommend moving the data to a new volume. You may wish to try running Microsoft's SQLIO to test the current volume, as well as a newly-created 2008 volume, and make your decision based on the results.
