Old data in database

hi,

I am continuing with the Evaluation .... !!

I found that the old data of routers / interfaces in the database cannot be removed even they are "Deleted" from the Lincese Management.

This lead to a problem that we are facing. After we change the source IP of one router, we try to delete the old records (the old data is not needed anymore) and rename the new IP with the same as the old one. (Same name). However, the system does not allow me to do so, probably because the same name has been used before (not unique).

Also, in the Device Group Management, I saw a lot of routers that no longer need to be monitored. These devices name / IP are just cannot be removed even I "Delete" them from the License Management.

Is there any method for me to remove them from the database?
