I think the answer will be yes, but want to make sure before proceeding with some R&D work.
Will Openedge 11.5 Application Servers (especially REST adapter) work without issue with a 10.2B database ? We are not currently in a position to upgrade the database, but need the REST functionality provided in 11.5.
Great thanks for confirming.
If you're using client-principle it is not possible I believe.
