This morning we started experiencing the following error during mirroring:
Mirroring state: Failure during importThe following errors occured:Exception: Specified part does not exist in the package.
Mirroring was been working without exceptions for a long period but today is constantly failing.
Does anybody have any ideas as what could be the cause or what to look out for?
Do I need to turn on logging in the source and target?
Mattias Lövström have a solution for it, which is worth to try. Alternatively you can enable logging on target site to see more details around the error message since the error is on target site (Failure during import).
Hope it helps.
