Rolling instances/ updating templates

[Googler]

Hello Googlers! 

Is it possible to change template of an instance group without changing VMs and vice versa ? 

Thanks, 

Khalid

Hi @Googler,

Welcome to the Google Cloud Community!

You can't update an existing instance template or change an instance template after it has been created. If an instance template goes out of date, or you need to make changes to the configuration, create a new instance template[1].

You can update the Instance Template of a Managed Instance Group by Selecting the MIG in Compute Engine > UPDATE VMS > Select your newly created Instance Template.

I hope this answers your question. Thank you.
