System requirements are listed in GroupWise System Requirements
in the GroupWise Installation Guide.
NOTE:We no longer support installing the GroupWise agents on SLES 12 SP4. If you want to install agents on SLES 12, you must first update to SLES 12 SP5. This is due to a SLES 12 SP4 incompatibility with our ICU library.
IMPORTANT:Before upgrading to 24.2, make sure your GroupWise server certificates pass the Certificate Verification
requirements in the GroupWise Administration Guide or you will have problems during/after the upgrade.
