The short answer is no, but there are subtle details.
There are three possible cases of how you can install the X-Cart 4 and X-Cart 5 stores.
- You install X-Cart 5 on the same server as X-Cart 4. In this case, everything will work. 
- You want to install X-Cart 5 on another server (some test server, local machine, etc.). If you transfer the entire X-Cart 4 store there, everything will work just fine as well. - To make X-Cart 4 transfer easier, you can only transfer X-Cart 4’s database and the following directories to save you some time: - <X-Cart>/images/;
- <X-Cart>/skin/common_files/pages/;
- <X-Cart>/files/(if you have e-goods).
 - Put the database to the MySQL server and place these directories inside a folder that would pretend to be X-Cart 4 for our migration task. 
- You want to install X-Cart 5 on a new server but keep X-Cart 4 on the old one. To make this case is possible, you need to: - make sure that the MySQL on X-Cart 4 server allows remote connections. Contact your hosting team about that if you face any troubles; 
- set the enable_copy_ext_images option in Migration Wizard’s settings to true.
