Upgrade Sequences
The FOXMAN-UN and FOX61x upgrade procedure requires to strictly follow the correct sequence of upgrading steps.
Non-observance could result in equipment damage.
Upgrading Embedded Software of FOX61x network elements from ESW released prior to R18 to ESW released with R18 before having upgraded FOXMAN-UN to R18 may result in incompatibility of FOXMAN-UN and FOX61x network elements software and cause unpredictable behavior.
→ Always upgrade FOXMAN-UN to R18 before upgrading any ESW of FOX61x network elements to R18.
Do not change any configuration of the FOX61x network elements during the network upgrade process.
→ The changes could be lost.
Please note:
FOXMAN-UN (including add-ons) of system release R18 require a RHEL 9.6 operating system.
Please note:
FOXMAN-UN R18 includes a new DIRAC version (18.0.0) vs. the one previously released with FOXMAN-UN R17A.
→ The DIRAC database of a previous R16B or R17A installation is compatible with the new R18 RHEL 9.6 server.
Please note:
Prior to the start of the upgrade procedure, it is strongly recommended to save the latest used NE configurations on the NE, then create a backup of every NE configuration by saving the NE configurations to disk.
