Well I’m finally replacing my well aged DS412+ with the DS1621+. The current DS412 is Ext4 and I’m going to be using BTRF on the new NAS. That being said I need to migrate about 8TB from old to the new and I’m dreading copying 8TB. What are the best options for a speedy migration? I fear the only option is to mount both shared on a computer and just do a straight copy. Are there any tools within Synology that would be suited to automate the data copy/migration? Or is there a 3rd party tool (aside from just doing FTP)? Do I need the computer? Can I just find the the old NAS on the network through the webui on the new one and just mount it directly and copy? What is the best way to do this? Thanks!!
