First, big thanks to @JonathanM and @JorgeB for your replies they lead me in the correct direction! Learned a good amount in this process. For anyone trying to do the same thing it is relatively easy and there are a few ways to do it.
 
1. Backup all the data in the share/drive I was removing. You technically could change the disks the share uses and then use the mover, but I only had a few gigs worth of docker config files. Stopped all docker containers and turned off auto-start.
2. Followed the 'The "Remove Drives Then Rebuild Parity" Method' here: Shrink Array | Unraid Docs
3. Upgraded NVME and setup as a single Cache Pool. Cache Disk | Unraid Docs
4. Made my appdata share only use the new Cache pool and uploaded my previously backed up docker configuration files.
5. Manually edited each docker container with default appdata directory for configurations.
