I once tried to drop in a newer version of grouper into GridGrouper, just to
try it.
It didn't work (not even v1.2).
I can't imagine that GridGrouper will change to a newer version, because the
software stack (which contains GridGrouper) is changing at the moment.
So changing the version of grouper is, unfortunately, not an option for us
right now.

There is probably not something like a database conversion tool, which
converts a grouper 1.1
database into a grouper 1.5 database or such, is there?

That sounds more elegant than the LDAP route, at least if the Atlassian tools
are the only ones consuming the grouper data. Yet again, version 1.1... :)

Thanks, I'll have a look.

Yeah, let's see. I guess I need to try it out.
Seems like there is no easy route.

Thanks for the input!
