We are currently using NPM 12.0.1, which is upgraded from older version (usage started from version 9 and has been gradually upgraded as new versions came out).
We have used custom properties as variables in alerts, i.e. SLA, CustomerName, etc.
When NPM was upgraded, alerts were (mostly) migrated to new variable format, i.e. ${NodeID} to ${N=SwisEntity;M=Node.NodeID}, etc.
However, variables of custom properties were not changed, which is logical because custom properties are custom made.
Is there way to mass change / migrate those variables of custom properties in alert actions?
