Encrypting an Existing Array - Problem

[Foleykins]

I watched the SpaceInvaderOne video on Encrypting an existing array linked here: 

 

 

 

I want to encrypt an existing array. I have cleared space on 2 disks in the array using unbalance and have also setup the SSL certificate functions.

 

I am at the step where with the array stopped  I need to create a new config, I wanted to preserve the current assignments and according to the video I should be offered a cache option. I only have the following options in Unraid 6.9.2: NONE, Array Slots, Pool Slots. 

 

I have a cache pool and I have a SSD for my VMs under pool devices. 

 

Do I create a new config and select preserve pool since there is no cache option similar to the video?

"Pools slots" replaces "cache" on older releases, because now Unraid supports multiple pools.
