== Preparing for Upgrading
|
|||
|
|
|
|||
|
|
Before you upgrade, be aware of the order in which you need to perform the upgrade steps. Also note potential issues
|
|||
|
|
that can occur within the upgrade process. In general, you must upgrade {project_name} server first, and then upgrade
|
|||
|
|
the adapters.
|
|||
|
|
|
|||
|
|
. Prior to applying the upgrade, handle any open transactions and delete the data/tx-object-store/ transaction directory.
|
|||
|
|
. Back up the old installation (configuration, themes, and so on).
|
|||
|
|
. Back up the database. For detailed information on how to back up the database, see the documentation for the relational
|
|||
|
|
database you’re using.
|
|||
|
|
. Upgrade {project_name} server.
|
|||
|
|
* Testing the upgrade in a non-production environment first, to prevent any installation issues from being exposed in
|
|||
|
|
production, is a best practice.
|
|||
|
|
* Be aware that after the upgrade the database will no longer be compatible with the old server
|
|||
|
|
* Ensure the upgraded server is functional before upgrading adapters in production.
|
|||
|
|
. If you need to revert the upgrade, first restore the old installation, and then restore the database from the backup copy.
|
|||
|
|
. Upgrade the adapters.
