Moving Sites with Zero Downtime?
I have been wondering if zero downtime is possible when moving sites from ABCHOST to EUKHOST.
Then I thought the following may work but not sure. Assumptions are that your ns1 & ns2 is pointing to ABCHOST
1. Set NS3 & NS4 to EUKHOST
2. After 24-48 or 72 hours swap values for NS1 and NS3, NS2 & NS4
3. Now ns1 & ns2 would be pointing to EUKHOST. ns3 & ns4 pointing to ABCHOST (current)
4. Once propagated, move your sites to EUKHOST and remove ns3 & ns4.
Would this work?. Can I achieve zero down time?.
