[Issue]: Incorrect CCS version support info #1350
Description
Type of issue
Inaccurate
What documentation page is affected
https://www.elastic.co/docs/solutions/search/cross-cluster-search#ccs-supported-configurations
What happened?
The above document (specifically the support grid) around CCS version support contradicts this other document, which has the correct support grid.
In particular, what is incorrect in https://www.elastic.co/docs/solutions/search/cross-cluster-search#ccs-supported-configurations is that it states that an 8.18 local cluster can query a 7.last (7.17) cluster. CCS only supports "previous minor". So the only 8.x version that supports 7.17 is 8.0.
Note that the grid with the error does accurately show that 9.0 local can query 8.18, which is the "8.last" associated with 9.0, so the 8.0<->7.17 pairing neesd to show the same thing.
We have gotten a query from a customer who was confused by the contradictory docs, so this should fixed ASAP.
