Hello,
in short, I’ve got an installation of a ucs domain master with kopano core and webapp on top of it, running on an old pc. The goal is to move the kopano installation to new vm, on which a ucs backup dc is installed so far. Another backup dc is installed on a second vm, which should replace the master later on.
All ucs servers are updated to the latest release and patches. Now, when I try to setup the kopano core app on the first backup dc, installation fails / hangs at 25% with messages “must_not_have_concurrent_operations”. Hm, I let the systems alone for 2 hours, still the same. After that, I restarted all servers and tried again, with same result. It doesn’t matter, from which server I start the installation, target was always the first backup dc, hang was always the same.
I decided to throw the second backup dc away, thinking may be this will help, but, no, only difference now it hangs by 50%.
So, I need some help here, anyone a solution to get the second kopano core installed?
