I currently have a Sharepoint 2010 two-tier environment (1 server running DB, 1 server running both WFE and app functions running on Server 2008 R2).
Ultimately, I'd like to scale the environment from a 2-tier to a 3-tier (running WFE and search query services on one server, and all other service applications on the other). I would like ultimately remove current 2008 R2 server from the farm, completely replacing it with the new 2 farm members (running Server 2012).
Can I simply?:
- build two new 2012 servers with required hardware specs
- install and patch Sharepoint 2010 on both of them to the current environment with the configuration (WFE and APP) respectively
- modify DNS and AAM to point to the new WFE
- run the Sharepoint 2010 deployment wizard to remove the current 2008 R2 WFE/App server from the farm
Will that work--am I naive in the complexity of this? Any major considerations I need to take into account (e.g., is there a need to rebuild User Profile)? I've found some good documentation on scaling out a two-tier to a three-tier environment, but nothing concerning removing the existing WFE/App after the scale-out, so I'm a little gun shy.
