Hi all! I have this issue as well. I’m running a 2960X switch stack on 15.2(2)E7.

@ktbyers I can still reproduce this in 03.06.06E (IOS-XE train, I’m hitting this on a C3650).

Note that I only have one user on this device and I’m trying to change its name.

switch#show run | i username
username admin privilege 15 secret 5 some_secret_crypted_password
switch#show archive config differences flash:/candidate_config.txt
!Contextual Config Diffs:
+username admin2 privilege 15 secret 5 same_secret_crypted_password
-username admin privilege 15 secret 5 same_secret_crypted_password

switch#configure replace flash:candidate_config.txt force revert trigger error 
This operation will remove all username related configurations with same name.Do you want to continue? [confirm]
