I  want to split my NAS in 2 with one going to my brother for his use and to do mutual off-site backups to.

This is a bit too complex for me which is why I'm hoping someone with more experience can help me set up a transfer plan to do this as efficiently as possible.

 

Hardware-wise I have enough stuff for 2 "new" complete PCs without having to tear down the old NAS. For HDDs, there are 2*6TB planned for parity + 2*4TB for data. On the old NAS there is 5*3TB (incl. parity) and ~8TB of data, roughly equally split 4 and 4 between my brother and I, so 1 parity + 1 data in the new systems should work.

However I have no idea how to do the juggling with licenses and software setups to get everything where it belongs.

 

I already set up 1 machine with a trial key, can I transfer the key from my old NAS to this machine? Or could I even just after the transfer of data is done, plug the old USB stick into the new machine and use it as normal even though for example the user configuration is completely different and it has a different number and sizes of drives?

 

Added complexity:

The reason I want to do the split now is that a few weeks ago after a parity check a drive on the old NAS got disabled. Having done an extended self test it has 0 read errors but 2 of the other drives have several. This is why I thought transferring the data away is the safest bet. However if someone wants to convince me to simply rebuild it onto itself I'll attach the diagnostics of that aswell. The issue of splitting it in 2 still remains though.
