Update instructions

This release supports updates from 5.5.5 to 5.6.0 only. For all previous releases, update to 5.5.5 first.

The order of steps in the update procedures is crucial. Please review the procedures in advance, and follow the instructions carefully.

Known issues

  • When you change the metatype configuration, the Service Impact database is updated to add or remove nodes. Depending on which items are changed, processing the changes can take 30-90 minutes in very large environments.
  • (IMP-836) After a metatype configuration change, related service events are not cleared. To work around the issue, remove and then re-add the dynamic service.
