Server Compatibility -- XDCR

Describe any compatibility issues between Sync Gateway and CB server

1. XDCR (refer to PRD for the painpoints)
2. Won’t work between two mobilke clusters. You have to have unidirectional XDCR with 1 read only cluster.  Direct to ISGR
3. Add link to DR/Migration with XDCR- refer to link. Can’t use for active standup. Decide if you want to move whats in the ISGR doc or copy

Background

Our current documentation is not very clear on the deployment recommendations when using XDCR with SGW . We have seen an uptick in number of questions related to this topic. 

Although we specify one-directional XDCR as the option , we are not clear that SGW in target cluster must be read-only mode. Also, the impact of convergence and enabling import-docs on the both clusters (that would effectively be write) .

Please refer to this customer escalation . Specifically, read comments from Adam Fraser which elaborates on the various cases and recommendations .
