Jonas,

Did you have any issues with the external database after import your XML onto the new instance? You mentioned having to add plug-ins again, but does the same apply to your external database?

* When it comes to JIRA cloud to server i am not fully confident, but i recently moved JIRA 6.2.1 server to a JIRA 6.3.15 server and noticed a bunch of stuff i assumed would just work. What i did: installed a brand new setup of JIRA 6.3.15, set it up on external database, installed all plugins we depended on, imported XML dump from old server, reindex and once restarted.. All plugins where still missing and had to be manually added once again. I am not sure if this applies to cloud as well, but if it did on server to server, i can only assume that. Also, cacerts will be replaced, server.xml (with custom ports setup), setenv.sh (assigned memory settings) that all have to be reapplied.
* Do not know Mastero..
