Migration tool differences between the two versions

I have to move some servers from Debian 8 to 9 and use new hardware. As I found out the ISPCopy would be the right tool, but I am not shure as it is noted "same OS version" does that mean Debian some Version to Debian newer version or Debian same version.
Also what the differenz between the Migration Kit Full version and normal Version and is the a discount for ISPConfig supporters
Is the a manual coming with the Kit or is ist enough self explaining?
Thank you

Rainer

 

Debian 8 to 9 should be fine for the copy tool, Debian to Ubuntu or CentOS wouldn't, for example.
I don't know what you mean by normal and full version. There is no discount for ISPConfig supporters and there is a tutorial available here: https://www.howtoforge.com/tutorial...-confixx-plesk-to-ispconfig-31-single-server/

 

Sorry I should learn reading, the lower price is for the update

Thanks
