I am on SharePoint 2013 Now. Recently migrated from 2010 to 2013. There was a Records center site which was also migrated. We Backed up the Records center sites database and restored it in SP 2013 and Mounted it to a web app.
Scenario: Original site where the live data was http://abc/xyz on this site's libraries we setup the retention policy of 4 years, everything which is 4 years should be moved to a Record center site which is http://abc/sites/xyz. Once a document is received at Record Center site it will stay there for 6 years and post that it will be permanently deleted.
What we did is, we backed up the content database of record center site and restored to SP2013 SQL and mounted it.
Now we're seeing all the folders / files got the date modified to the day we did mounted the database to web app.
I tried to make sure if original site has anything which is older than or equal to 4 years. I see folders have date older than 4 years but within them files have recent date, which means someone might have modified the files within the folders. but then folder's modified date shouldn't change ?
I am confused with the dates what i am seeing, did someone experienced something similar and have tried to make some concept, let me know..
