Outgoing migration set version is from 2019
Summary: On the migration page, the version to migrate is 11.1.13.0.0, but the current version of TEST is 11.13.24.04.0. See "version is wrong".
This message appears at the top of the window: "System detected current environment is out of sync with the target instance. Use Move All Changes option and apply to target instance to synchronize all configurations."
I Moved All Changes previously and it still had the 2019 version listed as the current version.
I deleted the old Migration Sets and now it's in process after clicking Move All Changes again.
When I click Move All Changes now it says: "Warning: You can't export your configurations now because another export or an import process is already running on your environment. Please try after some time." It's been processing for over an hour.
