What to expect

Upgrading your server

When you apply the upgrade, the enterprise server service shuts down and performs the upgrade tasks. When the upgrade tasks are complete, the enterprise server service starts up automatically. If you have more than one enterprise server, upgrade the master server first.

Most enterprise server upgrades take 5-10 minutes to complete. However, upgrades in larger environments may take 15-30 minutes or more, depending on the size of the environment.

Wait at least 24 hours before upgrading
If you recently upgraded to version 4.2.x from an earlier version, wait 24 hours after upgrading your authority server and all storage servers before upgrading to another version. This waiting period ensures that all post-upgrade migration processes are complete before you start another upgrade.
Known issue in version 4.2.3
Version 4.2.3 of the Code42 platform is affected by a known issue related to LDAP sync. In certain circumstances, this issue can cause data loss.

We recommend that you:

  1. Disable LDAP sync before upgrading to version 4.2.3.
  2. Enable LDAP sync only after upgrading to version 4.3.4 or later.
