This step is required when migrating a system from IOM 2.x to 3.2
Make sure that both database and IOM-images are set to the same time zone. IOM-images now always use the time zone "Etc/UTC". Before starting the migration process, the time zone for IOM database-user has to be changed as well.
ALTER USER "<user-name>" set TimeZone='Etc/UTC';
Superuser rights are required to make this change.
Depending on the version of IOM Helm Charts you are using, more migration steps might be necessary.
Please refer to Public Release Note - IOM Helm Charts 1.2.0 for more information.
