We did a test conversion in Apr 2020 and all was fine, but when we performed the live data conversion last weekend, we encounter an issue.

When trying to propagate the security from the System Database in Database setup, Propagating System Tables is not responding.

Have tried to rebuild the AS and CS data but still the same error.

I have successfully converted 2 other databases on the same server without this issue.

Any ideas or suggestions on how to fix this?
