I have a couple of laptops on which i want to have photo apps. Would like to combine storage of both devices as one single big instance. Is it possible to dockerise both laptops with same app ( immich for eg) and distribute the storage/database across both of them?

Current laptop has win 10 + docker. Nextcloud n immich date is about 700gb ( majority immich photos). Would be shifting to newer laptop with ubuntu mate. Whats the best possible way to transfer the data so that the system is up and running asap?

Edit. I dont have laptop backup, since data ( files n photos) are downloaded from google photos n drive n uploaded to immich n nextc. Nextcloud is configured to use host file system so that I actually see the files on c:\somefolder in file explorer. Also using sqlite since this is a personal family usage. Performance is never an issue.

Edit 2: Checking on net showed resilio synch. I guess that is the easiest way I found as of now.
