I have a task list with content that i wish to migrate to SP 2013. I have tried to save the list as a template, convert the stp file to cab and change productversion to 5 in manifest.xml but with no success.
Is there any way of doing this without purchasing any separate tools?
Your best bet would be to take a backup of the 2010 content database and attach it to a 2013 instance to upgrade the content. You should then be able to create a 2013 List Template which will be compatible. A bit tedious I realise, but it will work, whereas mucking about with the xml will be questionable at best.
You can create a template from a list in Sharepoint 2013, and compare the xml from both lists. That way you can see the differences and make the changes to convert your 2010 template to 2013
