Upgrading from IOS Version 12.2(25)SEE2 to IOS version 12.2(55)SE

[TDBAKERJR]

Hello,

I have a couple 3560-POE switches and a 3750G-POE that are on very old IOS.  I have looked through the release notes and did not find a definitive answer.  

Is it possible to upgrade from IOS Version 12.2(25)SEE2 to IOS version 12.2(55)SE and if so should I expect any problems?

Thanks in advance!

Yes, direct upgrade to 12.2(55)SE-train is do-able.  Things to do before the upgrade: 

1. Save the config externally; 
2. Read the Release Notes; and
3. Use the "archive download-sw" upgrade script and DO NOT use the old method of copying the BIN file only.  The "archive download-sw" requires the TAR file.
