Exchange 2013: Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms Fails with 'An unknown command-line [/PrepareSchema] was specified.'
Posted on 2014-09-09
I am migrating from Exchange 2007 to 2013 SP1 in an adopted environment. Exchange 2013 is being hosted on server 2012 R2. I have gone through prerequisites successfully, installed what needs to be but when it comes to running, from an elevated PS window " .\setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms" it starts but then fails "An unknown command-line [/PrepareSchema] was specified."
I am currently downloading a new Exchange 2013 SP1 from MSVLC but any help would be much appreciated.
