Preparing for your Web Services and Application migration

How do I preserve my data through the migration?

We recommend that you backup your data before a migration. Your data data is kept in place during a migration, therefore, you don't need to perform any special action for keeping existing data through a migration. However, if you need to rollback to the previous version after a migration is complete, you will need a data snapshot of the Cassandra database to complete the rollback process.

How do I preserve customization through the migration?

We recommend that you make a backup of the existing configuration before perfoming a migration. Migration between 8.5.1 and 8.5.2 includes a transition to embedded Jetty that uses different configuration files. The GWS service is configured from scratch, therefore, there is no automated migration of customizations. A different configuration files are used in 8.5.2, so existing customizations for 8.5.1 are maintained.
