Issues in SharePoint 2013 after Upgrade from SharePoint 2010

Question

I have recently migrated sharepoint 2010 web applicaiton to 2013 using database attach and detach methods. 
I have few issues and just wondering they are issues or not. 
I am running in compatible mode in 2013.
1.I am not able to make a copy of any existing webs which are migrated from 2010.
I browse to site content and structure from the site actions menu.
click on a site then click on the copy or move, then a pop up box with the list of sites appears. i pick one of them and click ok.
now it goes to copy or move operation then at the end it gives me following error
The current operation could not be completed. Try again, or contact your system administrator.
Object reference not set to an instance of an object.
You may re-try the operation, and you may need to clean up the half-created data first before re-trying. If the problem persists, please contact your system administrator.
User account used is the Farm account. 
This is from the logs:

I think its related to page layouts URL it will reference to old URL because you are using database attach and detach methods.
You will need to update the current page layout (Check below PS script)
