Hi, I am in the process of upgrading our webserver & need to change the dns mode on one of the servers to slave/secondardy for all domains, Is it possible to do this on mass or is it a case of doing all individually? Im using server 2008, plesk 10.2.0 on both. basicly I currently have 3 servers. 1 which is dieing which is currently the primary server the second has an out of date dns list / zones, & the third is a new build with new correct dns. What i want to do is set the second server as a slave to the third, so that eventually the first can be removed this will give me some breathing space incase the first one dies as the new build is currently not listed as a name server for any of the domains. Using this method i can still have the dns resolving correctly from a known good copy for as long as i need & dont have to worry about replication time when i do the final cut over. PS i should have mentioned the dns is flaky / corrupt on the primary thats the reason im not just migrating. Hope this makes sense.
