Mirror node version later than DC?

[Marcin]

Hello all,

I went trough

https://confluence.atlassian.com/bitbucketserver/smart-mirroring-776640046.html

https://confluence.atlassian.com/bitbucketserver/set-up-a-mirror-790632894.html

https://confluence.atlassian.com/bitbucketserver/set-up-and-configure-a-mirror-farm-978205589.html

and haven't found clear statement (or my understanding) can mirror version be later than DC nodes?

Example:

There is DC cluster running v 6.10

mirror nodes are v 6.7

As mirrors will expire sooner it that gonna work to upgrade them to let's say 7.11? Will they work with DC running 6.10?

Or I need to upgrade DC and then mirrors?

Thanks!
