So the easy answer is definitely just "don't do it". If you wanted to try, though, here's what I'd do:
1. Freeze activity on the new server 2. Systematically merge the user, repository, review group, etc. tables. This would require mapping any duplicates to their counterparts on the new server, and copying data for any missing ones. As you do this, update the pk fields on the old db in order to keep foreign keys matching (I'm making an assumption that the foreign keys have ON UPDATE CASCADE, which I really hope is true). Doing this through the python shell might be easier than with raw SQL. 3. Update all review request pks on the old server to not conflict with ones on the new. 4. Dump the database, filter out duplicates, and insert all the old data into the new db. This is probably a ton of work, and not a lot of benefit. -David On Wed, Feb 12, 2014 at 6:36 AM, Stephen Gallagher < step...@gallagherhome.com> wrote: > So, I suspect this is going to be a tricky situation to solve: > > I've been hosting a Review Board instance on Red Hat's public OpenShift > for quite a while while we worked on getting a supported version hosted > in the Fedora Hosted infrastructure.
