ZFS data from snv_b134 to fbsd

[Dick Hoogendijk]

  I want to transfer a lot of ZFS data from an old OpenSolaris ZFS 
mirror (v22) to a new FreeBSD-8.1 ZFs mirror (v14).
If I boot off the OpenSolaris boot CD and import both mirrors will the 
copying from v22 ZFS to v14 ZFS be harmless?
I'm not sure if this is teh right mailinglist for this question. Let me 
know.
