hi all,

I'm being tasked to scope an effort to change the IP addresses of all the servers in our test lab to conform with the IP range of the new site we are moving to...
Stand alone servers are easy...
But successfully changing a 46 node Openstack Newton environment seems impossible.
Am I better off scoping the rebuilding of the whole environment?

I'm thinking changes are needed on each node, each config file and network namespace, I'm thinking each openstack endpoint and many places in the mysql database are all going to need updates. Fortunately instances are expendable and mostly can all be rebuilt.

Anywhere else I am missing? Am I better off scoping the rebuilding of the whole environment?

I assume you have 46 node cluster , changing openstack service ip + you have might have 100 + instances would be challenging, if u compromising with data loss and safe your extra time, I would suggest go for rebuild environment. Let’s see what’s others opinion
