Newest version available on el7 is 2.2.36. You should be having no problems with updating minor versions. Or clone the production environment to a test environment and test the upgrade.

Thank you Aki for the reply.
But I cannot disturb the version at present as it is a live server and thousands of emails will circulate every hour.
Could you please suggest me how to create HA/resilience for the existing environment. I have another server ready with the similar configuration. Please provide any steps/link for me to proceed on this? It will be a great help to me.
Thanks, Kishore

You could consider using more recent version of dovecot. 2.2.10 is already over 5 years old.
