So, if I may more thoroughly explain : I'm a new hire here at this firm, tasked with upgrading the Subversion server from RHEL 5x to 7x. That was done successfully, but a user suggested I also upgrade the repos as well to benefit from the new server's features. The current server (from which I ran 'svnadmin upgrade') is 1.6.11. At the time, it was the only management server connected to NetApp (repos). Now, when users attempt any svn work, they get the error I reported in the ticket. So, now that I've added the new Subversion server (running 1.9.4) as a management server to NetApp, what should be my next move?

I have 200 repos, all production, so I'm sure you understand the need for accuracy here. Apologies for being such a newbie with this, but I'm being as cautious and informed as necessary. Thank you.

As stsp stated you first need to get grip of a 1.7.0-alpha build which
you can run against your repository. Given that s/o created the
repository with such an alpha version I'd guess that somewhere in your
company some backup of such a version should lie around somewhere. I'm
not aware of any publicly available binaries of such a version,
unfortunately. Worst case, you'll have to build such version from the
old source code (or s/o on this list can help out with that).

You then need to do an svnadmin dump with that particular alpha version
and the repository in question. When you got the dump, you'll setup a
fresh repository, set the UUID of the new repository to the old one and
do an svnadmin load with the 1.9.4 version of the previously stored dump
file into the new repository.
