Connecting 2 Time Capsules
I have 2 TCs, one is the latest (AC, i'll call it NEW) and 1 is the previous version (B/G/N, I'll call it OLD), both have 3TB storage and the old has another 2TB drive attached via USB.
I'm using the OLD one fine, backups via a partition (NAS) and time machine for several computers.
I bought the new one to not only extend my storage space, but also for better coverage throughout the 3 story home (basement, Main Level, 2nd Level).
I want the NEW one be the primary Router and eventually the primary NAS (~500GB) and for time machine backups.
I want to use the OLD as is -- for NAS storage, time machine, and include the 2TB external storage (used currently for 1 computer for time machine only). I've read up on extending a wireless network (wifi) and also how to configure via ethernet and put it into Bridge mode. BUT, I do not want to lose any data if it requires a hard reset to factory default, which is what I've read.
End result will look like this:
1) NEW TC is primary router with 3TB of new storage available. In Main level of home.
2) OLD TC extends the range in my home, whether it is wifi or via Ethernet (preferred). I might add the ethernet is going from the TC through a switch in the 2nd Level of the home
3) Keep existing external drive attached to OLD (don't mind moving this, but I lose a year's worth of Time Machine backup, not a big deal).
4) Preserve all data on OLD.
How can I accomplish this?
