Replication task from not encrypted to encrypted pool

[Matttt]

Hi everyone,
i'm going to migrate my data inside my new truenas server. In the old one the data are stored in a not encrypted pool, and the new one is encrypted. The problem is that the replication works only when the final pool is not encrypted (i tried and it worked). This is the error I receive:

Unable to send dataset ... to existing unrelated encrypted dataset

I have tried different solutions, searched on internet, but nothing worked. My two truenas are at the same version (the last stable).

Can you help me?
Thanks!
