I am hosting a number of websites that I am looking to move to new servers. I currently have a Varnish load balanacer that points at my current web backends. I am hoping to use this same LB to send domains to the new LB and then on to the new backends. I am hoping to move the websites in batches so I can ensure that they working and operational. I would like to be able to move the site/s and then tell the load balancer to route those specific domains until all have been migrated. I don't think this can be accomplished with Varnish but it may be possible with a different or additional program. Following the migration I will be moving the IP from the old LB to the new LB. I know I could update DNS records but this would not be the ideal way of doing things. Any help would be greatly appreciated. Thanks in advance
