Any there any special steps for upgrade from WSP 2.1 when using Exchange 2013? We’re not on the latest Rollup Update, but that isn’t difficult to fix. Its a 2 node DAG with both servers being multi-role on Server 2012 R2.
There are no special steps required if your currently using WSP 2.1. If you follow one our migration guides located at https://solidcp.com/kb/installation/ it will take you through the process.
