Suite two installations of vbulletin running at the same time using a single license
 

hey
i have a running installation of 4.02 on a server called XXX, and i would to upgrade it to 4.06
for that purpose i took a new server (with address YYYY) to test the upgrade procedure there. i took the db of the running 4.02 installation , imported it on the new server , and upgraded it there to 4.06.
suddenly the existing 4.02 installaiton which has no connection what so ever to the 4.06 one , started sending the "welcome to the forum" emails with the YYY address (??) inside. after awhile it the emails were back again sent with the right address.


why did this happen? does the customer number (the only thing linking those two servers) report the site address back to the system when sending mails ??

i only want a single production installation , the new server is only for testing purposes and i will be running them both for about a week, until i finish my testing.
