We have an old 5500 that has been acting as our vtp server for years. we plan to remove the 5500 soon. We have an 6500 that is running in client mode now, we wish to reverse the roles of the 6500 and 5500. Making the 6500 the server and the 5500 the client. Anything we should be careful in doing? Will it be as simple as making the 5500 transparent, making the 6500 the server, and then change the 5500 to a client?
having two VTP servers is not a problem is indeed recommended!
With this in mind, I would change VTP mode to server on the C6500 and I wouild look for another device to be elected server
C5500 can be kept in vtp mode server until you will power down it
Hope to help
