Thank you for reaching out to us!
If you want to upgrade your existing project to Sitefinity 4.3
first of all you’ll have to upgrade to Sitefinity 3.7 SP4 following these instructions
and then you’ll be able to use our Migration tool
to upgrade to Sitefinity 4.3. The reason why you have to upgrade to 3.7 is that the tool is not compatible with the previous version of Sitefinity 3.x.
For more information on how to do that you can watch this video:http://www.sitefinity.com/blogs/gabesumner/posts/11-08-16/ready_to_upgrade_from_sitefinity_3_x.aspx
. Moreover, you’ll be able to submit support tickets in case you encounter any difficulties during the migration process and our support engineers will be more than happy to assist you. Also you can always contact me and I will make sure that your request gets addressed promptly.
Also, I encourage you to attend a special webinar
that will demonstrate how to upgrade a Sitefinity 3.x web site to Sitefinity 4.x. This webinar will show how to use the migration tool to upgrade your web site to take advantage Sitefinity’s latest features
On a side note, I couldn't find a license activated under your account, could you please let me know who is the current license holder?
I hope that this information is helpful.Should you have further questions or concerns you can feel free to contact me directly at firstname.lastname@example.org
