Re: Database Persistence Backup

[toddmcgrath <mc...@supergloo.com>]

Hi,
I'm running into this same issue (see below).  What's the recommended way to
move from one database to the another?  I'm using 1.3.1,
BundledPersistenceManager and need to migrated from a local dev mysql to a
qa mysql db.

Thanks in advance
Todd

Hi,

I don't see any reason why this shouldn't work. However

- The repository must be closed before coping (source and target)

- The reference to the database must be changed in all config files
(repository.xml and workspaces/*/workspace.xml files)

- The files must be copied as well (directories 'repository',
'version', and 'workspaces') unless you use the same files of course

- Merging repositories or 'partial copy' is not possible in that way

- You can't easily migrate currently from one database product to
another (for example MySQL to PostgreSQL).

I hope this helps,
Thomas
