If you are switching to a new server within the current hosting provider or with a new provider, all that is required to do at Incapsula is to change the site IP address.
That is done accordingly:
1. Go to Settings
2. Origin Servers tab:
3. Edit /Remove the old server IP and enter the new server IP:
- There is no need to make any changes to the Incapsula DNS records.
The change is propagated to the various proxies and becomes active within a few minutes.
- Make sure to restrict direct access on the new origin servers and whitelist the Incapsula IP ranges only.
An updated list of Incapsula IP ranges and additional information can be found in this article.
