I am attempting to upgrade my RT instance from 3.8.7 to 4.0.0.
My elected approach is to set up the 4.0.0 instance alongside the original 3.8.7 instance (i.e. two separate databases), and verify that the 4.0.0 instance works properly before retiring the 3.8.7 one. I have successfully set up the 4.0.0 code base as a "new installation" via "make install," set up a separate MySQL database for 4.0.0 and copied the 3.8.7 schema into it. I understand that I need to apply a series of sequential upgrades to the copied database in order to make it a 4.0.0 schema and complete the 4.0.0 setup, but I can't see how this is done. The README document states in step 6b that "make upgrade" will provide the command necessary to upgrade the database. This implies a need to overwrite an existing code base--which, in my case, is not happening. Given my use case--one which I hadn't imagined would be all that uncommon--what is the correct approach to getting the database updated to the correct schema? (I apologise if this is explicitly covered somewhere in the docs. Things get harder to absorb as you read them over and over again...)
