Dataset and sub dataset removal

[Drifting]

Hope someone can help, and please do bear with my, I am new to Truenas, and also I am partially sighted, bit confused at the moment.
Anyway, have been running a basic FreeNas for quite a while without issue. I decided that I would wish to upgrade the machine, and second puit more storage in.
Having read that replication was the way to go, I thought I had set this up right. Seems not.
Old FreeNas had this structure \pool\store\store which has all my data in. No idea how I got the duplicate \pool\store\Store and would prefer all the data moved from \pool\store\store to just \pool\store. But also I do not want the last empty Store.
Hope that makes sense, very confused at the moment as I thought all I had to do was to go into the shell and remove the \pool\store\Store, then copy the contents of \pool\store\store to \pool\store.

So what I need to know is how to copy the contents of \pool\store\store to \pool\store and to remove the dataset \pool\store\Store

Hope that made sense to someone, I am exausted trying to get a crash course in Truenas, love the product, find it very confusing.

Kidest regards Pul

OK, so let's take it one at a time:

remove the dataset pool\store\Store

zfs destroy pool\store\Store

copy the contents of pool\store\store to pool\store

I think the easiest here is just to move the first store out of the way and move the second one into place...

zfs rename pool/store pool/temp-store
zfs rename pool/temp-store/store pool/store

You could (depending on what you wanted done with the additional level) then destroy temp-store also (after you confirm that pool/store has what you want in it)
zfs destroy pool/temp-store

Thank you so much for the reply. I seemed to have other permission issues after replication. So bit the bullet in the end and wiped the pool and started again..

Thank you for your help
