# This migration will create one row of NotificationSetting for each Member row
|
|
# It can take long time on big instances.
|
|
#
|
|
# This migration can be done online but with following effects:
|
|
# - during migration some users will receive notifications based on their global settings (project/group settings will be ignored)
|
|
# - its possible to get duplicate records for notification settings since we don't create uniq index yet
|
|
