If you are planning to consume Skylar One 12.5.20, be advised of the following:
- The 12.5.20 release is available as both an ISO and patch.
- All Python 2 functionality was removed from Skylar One with the 12.5.1 release. If you still use Python 2 for custom code, you cannot upgrade to this or any later releases until your custom code is Python 3-compatible.
- You can perform upgrades from one minor version to any later minor version within the 12.5.x series. However, as with all updates, ScienceLogic strongly recommends that you perform such upgrades in a test environment before implementing the upgrades in production environments.
- The ScienceLogic-validated upgrade paths to version 12.5.20 are outlined below.
- 12.5.7 > 12.5.20
- 12.5.5 > 12.5.20
- 12.5.4 > 12.5.20

- AWS deployments that are using Aurora 3 can upgrade to this release.
- The Enterprise Key Management Service (EKMS) is enabled by default in 12.5.20.
- There is a known issue impacting upgrades to 12.5.4 and later from the 12.3.4 through 12.3.6 releases that could result in deployment failure due to patch hook task issues. For more information about this issue as well as a workaround, see https://support.sciencelogic.com/s/article/20990.
- When upgrading Skylar One to version 12.5.20 from 12.3.x or earlier, PowerPacks that use legacy encryption will become read-only. This issue does not impact upgrades from previous 12.5.x releases. For more information about this issue, including resolution steps, see https://support.sciencelogic.com/s/article/20806.(Jira ID: EM-73018)
- If you currently use local authentication with an MD5-hashed password, you will be required to reset your password when upgrading to Skylar One 12.5.20.
- 2.5.20 adds a new, post-update cleanup script that removes old patch bundles to free space on the Database Server. This cleanup process can increase upgrade time during the first run, especially on systems with a large number of older patch bundles. To reduce upgrade time, you can pre-clean older patches before upgrading. For more information, see the section on System Update Enhancements.
