Our migration from 5.3sp1 to 2011sp1 will happen for period of 2-3 months, but content will be added on production during that time in tridion 5.3sp1. After the migration activities we will have migrated system on 2011sp1,
But now i want to migrate new content from production(which is still in 5.3) to upgraded DB.
Content porter version 2.3(currently being used in 5.3sp1 ) is not supported in 2011.
What would be the best approach for this?
I think best is to redo the database upgrade once again after production setup. At last stage of testing ask editors to add/edit content on both server simultaneously.
You must have to convince your editors for content freeze or minimal changes in last stage after final db upgrade. We found it hard so we added custom event code to track changes and revoke access rights of many editors.
