Might be a weird and a bit complicated question. I currently only have a 500GB SSD and want to move to a new 1TB one, but I don’t want to do a new installation, but copy everything over using Rsync using the technique of a system backup I found in the Arch Wiki. My installation is around 6 years old, switched from antergos to endeavour during that time.
Not quite sure, if it allows for my goals to complete the way I want to though. So I’m asking here. I’ve been researching like crazy, but don’t come to a conclusion.
I currently have 4 partitions and using ext4 as a filesystem, besides /boot of course.
Partitions are /boot, /root, /var and /home.
With this move I hope to be able to switch to btrfs though and only have 3 partitions, as I’ve found sepearating /root and /var has been an error and caused a few irritations during the years. I’d like to have them as one again, so that I only have /root and /home in addition to /boot.
Will it be possible to reintegrate /root and /var into one partition? How can I archieve it when copying over everything with rsync? Is it fine switching to btrfs on the new SSD?
I currently have the old SSD still in the PC and have the new SSD in an external housing connected via USB and just hope to switch, when everything works.
