Issue:
A target site has a list with links which refer to wrong URL.
Workaround:
Migration Manager does not process links during migration. So, you need to change URLs manually when migration completes.
Links are stored in database as a relative URL. If during migration only host name is changed the link is broken.
For example:
Source site has a list with the "Hyperlink or Picture" field type. And there is the following item:
When you perform migration of the http://ksps:81 site to a new target site collection with the http://kmoss/sites/OldRoot URL, the list has the following list item:
If a user tries to open the URL he sees error message, because the document URL now is http://kmoss/sites/OldRoot/Shared Documents/How it works.doc. The /sites/OldRoot part is not here
But if you migrate the http://ksps:81 site as a new root site collection (http://kmoss) (i.e. web application name is changed only), the link will work. In this case the link description stays original.
