Hope all is well with you.

Need your valuable advice, I have the below situation.

# Physical DC movement done.

# Change in Transit provider and change in IP address of AR's.

# Polling was disabled before the physical move for AR's and N/W devices.

# After physical move by mistake polling was enabled for the AR's, this has caused the loss of historic data captured for AR's by overwriting new data.

Question : Can we retain the old historic data of specific devices by copying the whole device RRD folder from backup, if not is there any other method.
