I have just been notified by my current NOC that they are going to have to move my server to a different NOC down the street, and that they are going to have to reassign me a totally new C Block of IP's to replace the current ones I am using.
Where do I go from here??? Please help!!! Here's what I've done so far with the limited knowledge and time that I have to get this done...
1) I was told what the new C Block of IP's are going to be at the new NOC, and I added them in using the feature in WHM as follows: 64.200.207.1-254. They are appearing as available in WHM.
2) I have had two main name servers setup (NS1 & NS2) that most of my customers have in their domain name records (minus a few resellers). I went into my Bulk Register account and changed the IP address on file for the NS2 name server to one of the IP's in the new C Block. My thoughts here are, NS1 is pointing to the old NOC and NS2 is pointing to the new NOC.
3) I used WHM to edit the DNS Zone for the domain name of my name servers and changed the NS2 IP to match the one in step 2 above.
4) I edited the /etc/hosts file and added the new IP of NS2 so it looks like this:
64.200.207.5 localhost.localdomain
127.0.0.1 localhost
128.241.245.19 saturn.yourhostserver.com saturn
157.238.132.4 localhost.localdomain
The IP on top is the new IP in NS2. The 3rd IP is currently the main IP of my server and will be changing to 64.200.207.2 (NOT SURE WHAT TO DO HERE. I mean I know I will have to change it above, but I'm trying to think ahead so as to avoid down time.)
The last IP up there is the IP on my main NS1 name server, and I have left that in tact so every thing stays running at the current NOC.
5) I then edited the /etc/resolv.conf file so it looks like this:
nameserver 127.0.0.1
nameserver 157.238.132.4 #Current NS1 IP.
nameserver 64.200.207.5 #New NS2 IP.
nameserver 128.241.245.19 #Current main IP.
nameserver 4.2.2.1 #Not sure what this is.
Does that look right so far? Do I need to do anything else??? Any other files I need to modify? OK... please stay with me a bit longer...
6) I have several resellers that have their own name servers on our system. So I basically did the same thing to their NS2 setting by changing the IP in their domain name / name server record to a new IP in the new C Block. I then updated their zone files in WHM and replaced the old IP on NS2 with the new IP from the new C block. I then restarted Bind.
&b&7) When they disconnect my server and drive it over to the new NOC and plug it into the new network, what do I do from there once I have root access again???&/b&
8) I need to reassign every customer on the server a new IP Address from the new C block. Do I do that using the WHM feature? If I do that, will it update the httpd.conf file and the zone files, and anything else that may need to be updated? Will it be as simple as that?
9) What about the few customers I have that have their own SSL certificates? When I assign them a new IP will their SSL IP be updated in the httpd.conf file?
10) Am I screwed here? How much down time do you think my customers will experience? Is there anything I can do to further minimize down time?
Any help that could be given by someone experienced would be greatly, greatly, greatly appreciated!!! Thanks in advance if anyone can help!
