that's what we currently do... BUT we are going to split them to run on different vm's - thus there needs to be a reverse proxy of some sort (reverse squid, haproxy... doesn't much matter :)). > If you do need to temporarily reverse proxy any website, as part of > migration, then Apache can do this individually on a per virtual host basis. > > > > By the sounds of it, top priority is migrating all services on e2 to a > > > vm on the e5 system.

Most > of these switchovers are done in under a minute. i know. :) i use rsync every day... been using it since like.. 1998 or so for my own homedir. :) it depends how much data needs to be copied and how lazy you are... and how good your link is. my link at home is 100mbit... so i get rather lazy (i can sustain 30mbit or so between home and e.org and that link goes across the pacific). :) it all depends on who does it. sure. rsync will do the job. :) just pointing out that the setup can be done "given current state/data" so all the right packages, config etc. is there and working and then just a "last minute update before switching" can be done... it can even be done direct from e2 to e5 that live in the same datacenter... :) 100mbit then :) -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
