Changing disk library for primary storage policy copy

Question

Hi there,

most likely we will need to temporarily change disk library for a couple of storage policies because of slow DDB database reconstruction.

My question is how to change disk library for primary storage policy copy? There is no scroll down menu to change disk library in Default Destionation field

Does it mean that I need to create new secondary copy and after that promote this newly created secondary copy to be the primary one? Is there any potential data loss? Do you have any hints or caveats for this task?

@drPhil, you pretty much answered it yourself: if you want to fully move everything over, create a Deduplicated aux copy, let it complete, then promote it (you can delete the original Primary if you wish after, assuming you need the space/library for something else or just let it age on its own time).You CAN add another library to the Data Paths, disable the old one for write, seal the store, then wait for those older baseline jobs to age off, but that will take a while depending on your retention.

Thanks, @Mike Struening. I have just one additional question. Then, after promoting the newly created secondary copy, is it posible after some time to revert changes and make old primary copy back to be the primary one?
