Fresh Exchange 2013 install on 2012 R2 RRS feed

  • Question

  • Hi Everyone-

    I'm a bit confused on the steps to install Exchange 2013 SP1 on 2012 R2 in a new environment (no 2013 installed).  I've seen many mixed install guides recommending I install non-sp1, preparing the domain/schema first, install CAS/MBX roles.  Once complete run the Sp1 upgrade starting with the domain/scheme upgrade, and then run the EXE.  

    I've also read that the 2013 SP1 download ( is a full version of Exchange and can be ran as a clean install - so essentially just preparing the domain/schema and run the install once.  I find this hard to believe as the ISO I've downloaded from VLSC is 3.5gb, yet the SP1 exe is 1.5gb.  

    Can anyone confirm which is the correct path to take?

  • Hi,
    Can't think of a good reason to install any other build of Exchange 2013 then SP1. The EX13 SP1 download is a full install and the only one that is supported on 2012 R2. The bits is packed in a different way so the download is smaller.
