### Failure excerpt

In `AsyncSearchActionIT.testCCSCheckCompatibility` and `TransportTermsEnumActionTests.TransportTermsEnumActionTests` the code assumes that it can send a request that uses the current transport version (see `DummyQueryBuilder` / `VersionedNamedWriteable` ) and that will always be incompatible with the `MINIMUM_CCS_VERSION`

However since the move to `TransportVersion` it is no longer the case that a node on the next node version will be incompatible with the previous node version (which is what `MINIMUM_CCS_VERSION` tracks). In fact, immediately after a version number they will be identical - that is, `TransportVersion.current()` will be the same version as `TransportVersion.MINIMUM_CCS_VERSION`

This causes these tests to fail until the transport version is bumped.

For the test to work within the current assumptions it would need to get a `TransportVersion` that is after `MINIMUM_CCS_VERSION`, but `TransportVersionUtils` doesn't offer a way to create such a version on the fly (it has to already exist).
