Subscription renewal - Possible to keep current versions of apps?

Hello!

We are using the Technical Communication Suite on a subscription basis (3-year agreement).

We are about to renew our agreement, but the version of FrameMaker that is included in the new TCS is not supported by some of our third-party tools yet.
Would it be possible to keep working with the version of FrameMaker that we are currently using for a while before switching to the new TCS?

Thank you
