I'm trying to move list of device from LMS 4.0.0 to Prime Inf 2.0. Procedure:
1) Make a backup of LMS 4.0
2) On the VM deployed LMS 4.2
3) Copy the backup to LMS 4.2
4) Patched LMS 4.2 to 4.2.2 and then to 4.2.4
5) With LMS 4.2.4 trying to copy a CSV file
Problem - some of the equipment lost its settings - username / password has changed to cisco / cisco + part of the equipment does not transferred to Prime Inf
Someone has an idea?
I've never seen LMS "make up" credentials like that. If you still have your original LMS 4.0 running, you could try to run an export using dcrcli (Device and Credentials Repository command line interface) and inspect the values in the resultant .csv file. Detailed instructions are here.
You could simply edit the csv file exported from LMS 4.2(4) to include the proper credentials. Are there so many different ones that this would be burdensome?
A best practice is to use a service account for LMS that's defined in AD and your TACACS or RADIUS AAA server.
