Migrate from VHCS2 on Server 1 to ispCP on Server 2

[DaSilva]

Luckily I had an image from the whole system just a few steps ago.
With the second try all customers are built correctly (have copied the "group" file before the update script).
Now I have a question to the webs:

In /var/www/virtual all customers only have a directory called "phptmp" in their domain. If I create a directory called "htdocs" and put a simple index.html in there I cannot open it because of error 404. Now what must I do to activate the normal web directories?
Thanks.
