Using Synology for photo management?

[Enquiries]

I am already using Synology DS918+, currently has 12 TB on SHR, will be upgrading that to 24TB. I want to start migrating my photos on Google Photos and iCloud to the NAS. I understand that DSM7 is still under beta testing. My question is as follow : should I hold off loading any photo to photo station or Moments until DSM 7 is fully released?

I am also running Plex server on the NAS also do not wish to let any bug creeps into my Plex recording.

thanks in advance
