A lot of articles online give very simple examples on Blue-Green deployments. However, how would data update be handled?
Say I have a column called Category
with values (A, B, C, D)
. In my next release I want to consolidate values (B, C) -> (E)
to handle a new logic. However something goes wrong and I need to rollback in the next release. At this point, the data seems salvageable.
What are ways to properly handle this kind of situations?
