Statistical Information in Confluence

[Navadeep]

Hi Atlassians,

I have 2 question please.

Question 1: Is there any way that we can get the statistical information from Confluence. I mean what was the amount of data that got added last 2 months ? 

Question 2: We are planning to perform Confluence upgrade from version 5 to version 6.

During this process, we have put the existing PROD environment in Read-Only and continued with the upgrade.[Due to some issues we have to rollback and continue some other day]

But, our client want to have a minimal time for Read-Only during the upgrade process for that 16-24 hours window(upgrade process)

In case we do not keep the current confluence in R/O mode and continue with the upgrade, data might get added in the current Confluence PROD during the 16-24 hour period. 

Is there any way that we can manually copy the changes that happened during the 16-24 hour period ? 

Please provide your comments. Kindly let me know if you need any other information in this regard.

Best Regards,

Nav
