On DataMiner 10.3, I utilized the 'Clean up Unused Protocols Tool within System Center and inadvertently removed certain loaded protocols. Unfortunately, one of the protocol versions I deleted was in active use by some elements in production. I'm puzzled as to why this protocol version was listed as 'unused' when it was clearly in use.
After deleting the protocol, I encountered an error message stating: 'No valid protocol was found for the element'.
I'm aware that I can recover the deleted protocol from the recycle bin, but I'm curious if there is a way to restore the configurations of the affected elements back to their previous state before the protocol was deleted as well as the DCF connections.
I believe the recycle bin is the way to do this. Unless you work in a CI/CD fashion where you could re-load your whole configuration from a .dmapp package and script.
