I have about 2TB of various data that I want to sync between 5 servers (well, RW between 4 and RO to a 5th). I have two options before moving the drives out to the sites: 1) just prep a folder by copying the already being synced folder over to the drive, then setting up a sync on site on the remote server with the drive attached, using the Key and pointing it to the local folder with the data already in it. Will there be issues with the hidden files that were copied over causing any conflicts? 2) Use a local machine as a Sync Peer, and once the sync is up to date over the LAN, move that drive (but not the client) over to the other servers and set up the jobs using the Key and pointing it to the now-local folder. Will this have an issue as a result of the Peer change? If I decide to change a Peer to a Read-Only peer do I just do that by installing the RO key in place of the RW key? And the same for the reverse (I might set up everything as RO and make sure everything is syncing in one direction, then reset the Keys to RW once I'm sure everything is getting updated properly).
