I'll give it a try tonight and hopefully dont mess this up.
Is the data of shares, where I did choose "yes" for the caching option also present on the disk array, once move did his job? Or will there be data left on the cache? My understanding is, that only "Prefer & Only" keep data on the cash beyond a mover run.
I still struggle to understand the flow of data between cache and the array.
With the increasing usage of SSDs I think this could be a feature ("Cache Migrator") that would be usefull for a lot of users.
