Im currently planning on a few server upgrades:

 

1. Replacing the cpu

2. Switching my cache drive for a larger SSD

3. Moving to a larger case

 

What special considerations should be given when making these changes? I want to minimize the chance of losing data or creating more problems as a result of changing hardware

I guess im mostly wondering about 1) how to move my current cache contents to the new SSD without breaking anything, and 2) whether plugging hard drives into different SATA ports will cause any issues with shares?

No issues, Unraid recognizes disks by serial number.
