During Fresh Install of 12.1.6 with older version recovery files giving message "recovery file is missing some required settings"

I have a SEPM 12.1.4013 Server, we need to Migrate the it to the new Server with SEPM 12.1.6 MP4.

1) What is the Best Practice to do it

2) If I try to Restore Recovery Config files of 12.1.4 over the Installation of 12.1.6, During install message "recovery file is missing some required settings" is showing. 

What Shall I do, I do not wish to Install same version of SEPM first and then do the Migration and Disaster recovery best Practice procedure. I just would like to retreive the older config for ver 12.1.4013 to ver 12.1.6. what info I will miss with this install. 

Please suggest or adivce for the same. 

Any or All help is appreciated.

Thanks.
