1. backup the project's database (from 11.0)
2. restore the project dataabse to the database of 11.5
3.backup/copy the project's repository which contain the project's dbid.xml to the 11.5 repository
4.edit the dbid.xml to point to the new repository/physical path and the new database location/name
5.in site admin right-click restore project and point to your project's dbid.xml
6.then in maintain project do the validate repair upgrade
you can try this for one project first.
if in restoring the project will give you error regarding database do :
On the proj database run the query :
- exec sp_change_users_login ‘Report’
- exec sp_change_users_login ‘Update_One’, ‘td’, ‘td’
