So i recently wanted to upgrade my server from 120gb ssd samsung evo 840 to a 250gb ssd samsung evo 840.(OS DRIVE) My intention was to install windows 8.1, use the gatherosstate after it had been activated. Now when i installed windows 10 it was already activated when i wanted to place the .xml file after the SSD swap. Any thougts about this? I'm thinking it may be okay to swap hdd/ssd or any other hardware as long its brand is in the range of the old replacement? In that way m$ can accept still to activate currently hardware?
