Hello Andy, All
Regarding the "Server Error (500)" of the Central MA I think I might
found the reason for it in the yum update history.
"Scriptlet output:
1 No old data to migrate in /var/lib/pgsql/data, init
/var/lib/pgsql/9.5/data."
Well the main problem is that the data was in a different directory
"/store/pgsql/data" and since the script didn't find it it just created
a new one in "/var/lib/pgsql/9.5/data"
Can you tell me how to migrate the data to the new postgresql?
And should both new and old versions of postgresql be running or only
the new one?
Thanks in adanced!
