Customer has a 3 cabinet Legend R2 with a 100D in the last slot of the third cabinet. They are no longer using their PRI and want to replace it with an 012 T&R board. If I remove the 100 D board, install the 012 in its place and do a board renumber, will that automatically erase any PRI programming associated with the 100D in that slot? Any caveats other than the normal shutdown/powerup sequence? Thank you.
