How do we perform
database schema upgrade? Currently I am doing it manually by
calling each of the
upgrade_from_<from>_to_<to>.sql version files.
Does calendarserver_upgrade take care of it? If not, is
there an easier way of doing it?
Yes, calendarserver_upgrade has one job: to apply any
necessary schema and data version upgrades. It is intended to
be used immediately after upgrading to a newer version, before
the service is started.
Currently for upgrading from 3.2 files
to 5.1 db backend, I am just creating a new db. And the
migration from 3.2 files backend to 5.1 db seems to work fine.
Is there anything else that I should take care?
That sounds like a workable strategy for this upgrade delta.
Going forward, calendarserver_upgrade should be all that is
needed.
