The migration to the new OS is organised in three consecutive phases. It is expected to be complete by the end of July September.
The first phase starts with 2 login nodes and 112 compute nodes already migrated to Rocky Linux 9 for testing. The other nodes remain available under CentOS 7 for continued production.
After the test phase, a major fraction of nodes will be switched to Rocky Linux 9 to allow for general job production under the new OS.
During the last phase, only a few nodes still remain under CentOS 7. At the very end, they will be migrated to Rocky Linux 9, too.
During the migration phase the use of Rocky Linux 9 "clx" compute nodes will be was free of charge.
