This sounds good, however, I am getting these errors:
A transaction is still active in ldb context [0x2968680] on
A transaction is still active in ldb context [0x3d74120] on
A transaction is still active in ldb context [0x3023060] on
A transaction is still active in ldb context [0x40ce300] on
nothing is using those files, so I'm guessing there are some stale locks
somewhere. How do I clear those out?
And to verify, I'm just doing this:
upgradeprovision --realm=BAR.COM -U Administrator
I don't want the full provision, which sounds like it will wipe out everything,
