BIG-IP Install/Upgrade, TMOS
Known Affected Versions:
12.1.0, 12.1.0 HF1, 12.1.0 HF2, 12.1.1, 12.1.1 HF1, 12.1.1 HF2, 12.1.2, 12.1.2 HF1, 12.1.2 HF2
Opened: May 30, 2017
After upgrade from 10.2.4 to 12.1.2, full config load fails.
After upgrade, if changes are made to the running config (in memory; not on disk), then the config files on disk from upgrade cannot be restored.
The pre-upgrade version must be 10.2.4 and the pre-upgrade config must have user-defined partitions.
10.2.4 config on upgrade is stored at /config/bigpipe/. So, a workaround is to load defaults, then merge the original config using bigpipe. /usr/libexec/bigpipe merge /config/bigpipe/*.conf
Full load after upgrade from 10.2.4 now succeeds.
