Unable to migrate SiteStudio settings to Sitebuilder.

Unable to migrate SiteStudio settings to Sitebuilder in H-Sphere

Hi,

We are using Hsphere v3.4.1 and our SiteBuilder info is as given below. H-Sphere CP is installed on a Linux server.

======================
Product name : Parallels Plesk Sitebuilder for Linux/Unix
Product version : 4.5.0 Hotfix-20110711 (2011071115)
======================

We are trying to migrate a domain from SiteStudio to Sitebuilder but gives the following error. The domain in question is hosted on a Windows environment whereas the same works like charm for any account hosted on linux.

==============
Internal Error, Tech Support Was Notified.
==============

Does SiteStudio to SiteBuilder migration work for a Windows domain hosted on H-Sphere Control Panel installed in a Linux environment with Parallels Plesk Sitebuilder for Linux/Unix?

Any thoughts on this?

Thanks
