I've completed an upgrade/migration from OCUM 5.1 on Windows to OCUM5.2 on Linux - installed 5.2, backed up the DB on the 5.1 instance, restored it to the 5.2 instance, all seemed to work OK. Looks like all the settings came over, it seems to have picked up monitoring (mostly), all looks good.
I noticed that not all the events came over - the 5.1 instance shows 5 errors and 44 warnings, the 5.2 instance shows 1 and 26. At first I thought that old events from the 5.1 version that were no longer in effect (volumes full alerts that been resolved, for example) had been excluded, but that doesn't seem to be the case. The 5.1 version shows a volume that is 93% full, and shows the current warning alert of volume almost full (triggered 29 Jul 2013). The 5.2 instance shows the same volume at the same utilization, but doesn't list any alerts - so not only did the 5.1 alert not carry over in the migration, the 5.2 version has not noticed that the volume is above the warning threshhold and generated its own alert.
Checking the age of the oldest alerts, the 5.2 version goes to 12 Aug 2013. The 5.1 version goes to 31 Aug 2012, but before the 12 Aug 2013 alerts, the next oldest is 29 July - I restored the DB on 29 Jan, so did it's possible it just dropped everything older than 6 months? Even if that was the case, shouldn't it re-alert on the events that are still in effect?
Thanks
Bill
