Recently my team did a sharepoint migration from 2013 to 2016. We used the Attach and Detach method for the database from SQL Server 2008r2 to SQL Server 2012. It was successful however the database size has increased by about 3 times.
When i take a look at the database files there is duplicated files. In 2008 database there is 2 files but in 2013 there is 6 files causing the increase of 3 times.The 2 files duplicated by 3 so now i have 6 files.
I would like to have an explanation. Is there anyone who know what cause the file to duplicate or a link to an article regarding this?
In addition i would also like to know how can i resize the database size back to how i was? Meaning i would like it to be back to its original size.
Thank you very much.
