Any opinions on the best approach to merging two systems into one? Backup/restore isn’t likely to be a simple option as it would need to renumber all the tickets from (at least) one system. I had a brief look at the imports from other systems, but it doesn’t look like they could be used for a merge either.
One system is bigger than the other, so I could just start piping new tickets to the second system, but it would be nice to be able to keep the history intact.
Please note that this technically is not exactly supported and requires usage of import_mode and a maintenance frame for the migration on going until import_mode been disabled.
Sorry this is vague but it’s to protect our copy cats.
