You can copy RRDs from backups. If port layout has changed, likely ifindexes have changed, and so you’d need to match these up, which is troublesome.
Normally doing this sort of thing I’d add the new location as a new devie, and leave the old one disabled to retain historical data for some period of time.

Dear Experts,
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.
Thanks & Regards
