Link issue in migrated site collection

  When I migrate SharePoint site collection from one farm to another farm, then all the link (embedded) in documents are changed after migration.

For example.

Before migration – the link in a work document let’s say http://mysite.test.com/sites/100/Home.aspx

After migration – link is http://mysite-new.test.com/sites/100/Home.aspx

I am using  below step for migrating site collection from one farm to another farm (it is used for bulk migration)

1.       First we create temp database in old farm

Let’s say “MY_CONTENT_TEMP”

1.       Move the site collection to newly created temp database using “Move-SPSite” command

Move-SPSite "http://mysite.test.com/sites/100" -DestinationDatabase " MY_CONTENT_TEMP "

1.       After completion of movement we de-attach the temp database in old farm
2.       Then we migrate the database to new farm i.e. new SQL server with help database admin team
3.       After migration to new SQL server, we attach the content database to new farm
