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

it have around 10 domains and each domain is having around 20 email 
boxes. It has very simple configuration.

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