Adam Monsen updated MIFOS-2896:
-------------------------------
Description:
All current database upgrades must have a sequence number. This prevents
branch-based schema changes. We were originally looking at Liquibase to solve
this problem, but we now believe that the following can be done to add
non-sequential database upgrades to Mifos:
* register every database upgrade in DatabaseVersionPersistence, including
SQL-only upgrade scripts
* give each upgrade a unique name (can be anything... for simplicity, use the
existing database version numbers)
* the upgrade functionality (and associated tests) must be modified to support
upgrades in sequence, such that, given database versions "1", "2", and "3", I
can, on a branch, insert upgrade "2-v1.5.x", and specify that this upgrade must
be applied after "2" and before "3".
Team: (was: Core)
Summary: Non-sequential database upgrade (was: Non sequential db
