Sync Gateway 2.0 is known as a hard requirement to CBL DB22. My question is, is there any known compatibility between Sync Gateway 2.0 and CBL DB <22. Also; is there any question or worry of lapses in future forward compatibility, ie Sync Gateway 2.0 being obsolete for CBL DB > ##? We are doing some scaling exercises in our production environment and its a pretty major thing to temporarily shut down sync for a major Sync Gateway bump
SGW 2.0 will continue to be backwards compatible with older versions of CBL 1.x client. You can check out our compatibility matrix
