I have a number of 2821 routers I recently upgraded to 15.1.1 without any issues. One of the things I had to check is the amount of DRAM required. I also needed a new CF so I purchased a 2Gb CF, swapped out the rest and restarted the router.
One big issue to migrate to version 15 is security purpose, as the MITRE group has found and published a vulnerability list for Cisco IOS versions 12.4 and most if not all the recommended fixes is to upgrade to 15.1M, here are just some of the major links for the security vulnerabilities for DoS attacks on IOS 12.4.
