Follow the steps described below to upgrade Teamwork Cloud to a new version and migrate its database.

Warning
titleDatabase migration prerequisites

The steps below apply only when migrating the Teamwork Cloud database from versions 2021x, 2021x Refresh1, and 2021x Refresh2. If you want to migrate the database of an earlier version, first migrate it to 2021x series. When migrating skip the project migration step on the client-side (this step will be required only after the migration to the new version of Teamwork Cloud).

For more information about migrating the Teamwork Cloud database to 2021x series, see:


To upgrade Teamwork Cloud and migrate the database

  1. Upgrade Apache Cassandra to version 4.x (we recommend using Apache Cassandra 4.0.3).

  2. Upgrade Teamwork Cloud. After upgrading, the database schema will be updated automatically on the first Teamwork Cloud start-up.

  3. Migrate Teamwork Cloud projects.


Note
titleNote on usernames

When migrating from a pre-2022x Refresh1 Teamwork Cloud server, ensure that you delete duplicate external LDAP users with usernames in different cases (e.g., JOHN and john) if such usernames exist. Leave just one user. Otherwise, authentication of these duplicate user entries might fail in 2022x Refresh1.
