# If a Terraform state was created before versioning support was
|
|
# introduced, it will have a single version record whose file
|
|
# uses a legacy naming scheme in object storage. To update
|
|
# these states and versions to use the new behaviour, we must do
|
|
# the following when creating the next version:
|
|
#
|
|
# * Read the current, non-versioned file from the old location.
|
|
# * Update the :versioning_enabled flag, which determines the
|
|
# naming scheme
|
|
# * Resave the existing file with the updated name and location,
|
|
# using a version number one prior to the new version
|
|
# * Create the new version as normal
|
|
#
|
|
# This migration only needs to happen once for each state, from
|
|
# then on the state will behave as if it was always versioned.
|
|
#
|
|
# The code can be removed in the next major version (14.0), after
|
|
# which any states that haven't been migrated will need to be
|
|
# recreated: https://gitlab.com/gitlab-org/gitlab/-/issues/258960
