Migrate 2 DB's - v8.3

[Jeff Baldwin <tarheeljeff@xxxxxxxxx>]

Hello,

I am working to migrate 2 DB's (not the entire postgres instance), from 1 host to another... and I need some guidance on the best approach/practice.

I have migrated ~25 other DB's in this environment, and I was able to use pg_dump/pgrestore for those, and it worked fine.  These final 2 are live DB's, and I need to move them with minimal downtime (1-2hrs is acceptable).

The DB's are blob DB's that are 45 and 90G in size, and are in the same Data Center, with 1G connection in between

I am running postres 8.3 (I know :) ), so there may be some limitations there as well.   

Any help/guidance on the best way to approach this, are greatly appreciated.

Kind Regards,

Jeff
