My nextcloud is running well, still on 13 (I am waiting for passman to be ready to update). When I installed my NC I used an old HDD for the system disk (I have proper HDDs for the data), but I think it is now a bottleneck. That is why I now want to switch this old system HDD with a brand new SSD. The thing is it took me quite a time to setup everything. Is there a smooth way to switch without trouble? What is the proper way to do that?
I search for already answered similar questions, but did not find anything (maybe I missed something, if so, please link the question here, thanks).
Is it possible to just full backup, switch OS disk, install OS on it and restore backup?
Details: I am using ubuntu server 16LTS.
Thank you very much for trying to help me !
