Upgrade PTools from 8.53 to 8.56 for CRM 9.0
We're looking into the possibility of upgrading PTools from 8.53 to 8.56 for our CRM 9.0 application. We don't plan to upgrade the application. Is CRM 9.0 compatible with PT 8.56? If not, what will be the latest PTools version that is compatible with CRM 9.0. Is there an upgrade path this PTools upgrade? Any recommendations or suggestions may be helpful.
Thank You.
