A little more reading was required on your part.
From:
https://wiki.contribs.org/Affa#tab=For_SME9SME server 'rise' function
Note:
Before trying a rise please check /var/affa/YourServer/rpms-missing.txt
You may find there are missing rpms/contribs that template fragments depends on.
It may be necessary to install some of these rpms before a rise to prevent issues.
PS
It even says about it here, in the very article you referred to, so you do need to read these docs more carefully.
https://wiki.contribs.org/Moving_SME_to_new_Hardwareunder the Copying data section
You will find a list of RPMs which are installed on prodIP but not on this server (newIP) and also RPMs installed with different versions. Install or update the listed RPMs. To verify, you can run the steps of this chapter again. Finally the rpms-missing.txt should not list any RPMs.
