We are trying to use following combination of OpenDeploy version for Base and Receiver.
1. TeamSite -- OpenDeploy Base 7.3.2
2. OpenDeploy Receiver 6.7.2
Please, let us know if someone tried following combination and it's working for them.
In general - OpenDeploy should work in both up-rev and down-rev deployments (they put a bunch of effort into that since version 5.5.1).
Over the years, there have been occasional releases which had problems with one or the other mixed-release deployments, but they were all (I believe) later fixed with patches.
So - in general - it should work, but if you notice problems you should open a case with Support ... or upgrade the receivers...
