Hello,
I have recovered some configuration files from my 2950 switches with the Configuration Archive Tool in LMS.
Now, I'd like to replace my old 2950s by 2960 switches, which have the same number of ports.
Will there be any issue if I copy the exact same config from 2950 to 2960 ? Will some features not work or is everything interoperable ?
Here's an extract of the config :
Global
version 12.1
no service pad
service timestamps debug datetime
service timestamps log datetime
no service password-encryption
hostname sw48
logging buffered 20000 debugging
enable secret 5 ********
enable password ********

clock summer-time UTC recurring last Sun Mar 2:00 last Sun Oct 3:00

Thank you for your further help !

The 2960 is just an upgrade of the 2950 switch much like the 2960S is an upgrade of the 2960 so there should be no major problems unless there are some weird commands on the interfaces themselves. Nothing shown above looks like it wouldn't work to me.
You may want to go through the config a little, having enable secret and enable password is worthless, only keep enable secret, it is more secure. service password-encryption and some ACL's on SNMP might also be worth considering, depends how security concencious you are. Also the new enable secret
If you do come across a line of unsupported config the 2960 should give a warning or error anyway, things don't go boom and blow blue smoke, most of the time anyway.

Thank you for your help !
I have successfully copied the configuration and it seems to work well on my 2960.
Time to do this for the other 30 switches I need to change... Thanks to LMS !
