Subversion required - What other options are out there to replace FishEye and Crucible?

[MEDITECH ADMIN TEAM]

I am beginning the long search for a replacement tool for FishEye and Crucible. Given Atlassian moving to maintenance mode for FishEye and Crucible, what are other options out in the wild for replacing those two software offerings? We are set on SVN, so that eliminates GIT and BitBucket.

Im asking because with quick searches it seems its a move to GIT or there is not a wide set of offerings, if any. Anyone have some ideas or heading down this same path? Hoping we are not that different! HA!

There's a very good guide how to migrate from Subversion to Git:
