Migration to new Site Server

Hi All , 

I am in the phase of testing upgrade of  SMP to 7.5 SP1 HF3. And before upgrade i am planning on moving/migrating my existing site server to a new environment .

The main reason for the migration is due to low disk space . I use deployment solutions and store multiple images in my site server 

Any suggestions for the new server setup ??

Also recommendation on migrating the existing packages and settings to the new server ..

Thank You All in Advance 

Regards ,
