I have installed SP 2013 SP1 on windows server 2008 R2 many times. and now i will do my first SP 2013 installation inside windows server 2012 R2 instead of windows server 2008 R2. so i need to know if i can follow the same hardware specification i am currently using, or installing SP 2013 under windows server 2012 requires more RAM , processors and disk space ? or the differences are not that much ?
Thanks
