I want to update my current iMac OS from El Cap 10.11 to higher macOS. What is the best way to go about updating my current system?
Should I update to macOS Sierra or can I go higher to Big Sur?

The 2010 iMac can be upgraded to macOS 10.13 High Sierra and no further.

How to Upgrade macOS:
The macOS version you can upgrade to depends on the year your Mac was released.
Click the (Apple) menu at the top of your screen and choose About This Mac.
Check the Compatibility of your Mac with newer versions of macOS:
➡️ macOS 10.13 High Sierra is compatible with the Macs listed here
✅ - IF your Mac and apps are compatible, then using Safari only, download the macOS upgrade installer app:
Click > High Sierra.
Once downloaded, double-click the “Install macOS…” app in the Applications folder to begin the upgrade.
Please see > How to download macOS.
The end of the line for a Mid 2010 iMac would be macOS High Sierra (10.13).
