Delete plugin caches before JIRA upgrade?

Hi All

i am planning to upgrade my JIRA from 6.X to 7.0. 

My question - is it a good practice/recommended to delete the plugin caches before you do the upgrade?

In my opinion, If we delete then it prevents lot of unnecessary error logs during upgrade and guarantees that your indexes will be rebuilt. Correct me if i am wrong.

It won't hurt but it is not a necessary thing to do. Some things like indexes are always rebuilt during an upgrade. And the plugin cache will be updated when the new version of the plugins are installed.

I can't think of a scenario where I ran into an issue during upgrade due to stale cache. I have come across stale cache issue at other times though and you will find some KB articles around that if you search. 

Would be interested to hear from other experts too on this one. As they say, no two upgrades are the same!

Thanks Jobin for the response.
