IMac 21.5 inch Mid 2011 Is it relevant?

Running Hi Sierra 10.13.6 ; Can I upgrade safely to Catalina (10.15) or newer.? It appears every day now Google Meet, Formstack Sign or som type of correspondence is not being supported by my OS . Any Suggestions? Other than empty the piggy and go buy new?

High Sierra is the last possible. See the following from Identify your iMac model - Apple Support

iMac (21.5-inch, Mid 2011)

Model Identifier: iMac12,1

Part Number: MC309xx/A, MC812xx/A

Chrome still supports their latest browser version on High Sierra so that may help. See: https://support.google.com/chrome/a/answer/7100626?hl=en
