Site Pairing Zerto 9.0 ZVM to Zerto 8.5 ZVM

Has anyone attempted to pair a version 9 ZVM to version 8.5?
How to pair with the new pairing changes after 7.5: https://help.zerto.com/kb/000003776
What I can tell you from my experience is to ensure that TLS is matching on all ZVMs and Hosts. (double check site versions, clocks, don’t be on 7.0U3, etc)
Here is how to check: https://www.waco-texas.com/userfiles/cms-water/file/how_to_change_TLS_settings.pdf

Always check the interoperability matrix: (https://s3.amazonaws.com/zertodownload_docs/Latest/Zerto%20Virtual%20Replication%20Operability%20Matrix.pdf.)
And read the release notes:
The information from Derek A doesn’t answer my question. I work for a CSP, and my question is, “can I pair a Zerto 9 ZVM to a Zerto 8.5 ZVM?” I’m not yet looking to upgrade to Zerto 9 within our infrastructure.
Customer has Zerto 9
We have Zerto 8.5
Can I pair, or were there new changes in the pairing tokens that won’t allow it?
Thank you, there were a few details missing like what platform to what platform, and whether there is a ZCC in path. I believe you are referring to the changes that happened in 7.5 to beef up security.

I have not seen nor heard of issues with my CSPs pairing from customers on prem from 9 to 8.5 cloud recovery. If you need an NFR key to try it out in your lab please contact your Cloud Architect or Cloud Account Manager.
Yes you can pair ZVM 9.0 and ZVM 8.5. No change in pairing tokens.
I have successfully pairing multiple ZVM.
