To upgrade to Sierra up need a

El Capitan

you saved him greatly lllaass!

Macs from 2011 CAN run Sierra, but need to start from something later than 10.6.8.

So to summarize what lllaass said:

1) upgrade to a later Mac OS. If you do not have a different one already available, use the free ElCapitan. Download and Install it on your iMac.

2) once you are running ElCapitan, you can easily upgrade to Sierra.
