The original server is a production server not connected to internet. Due to update it i have to connect it but i have to stop it from production from the necessary time.. but i don't know how much is the necessary time..
It has some personalized settings such as php 5.4 with many optional library..
Last time i tryed to upgrade a small test server we have from 6.5 to 6.6 beta we lost some personalized settings.
Now i will have to do 2 update: 6.5 to 6.6 and 6.6 to 6.7 but i'm not very sure to update.. if one of the update compromise the server functionality the entire restore of the backup can take some hours ! It's a huge of time of production stop.. for my point of view it's risky.. tipically this server born, still in production for 5 years and die (taken out of service) with the same os. If a failure occur a twin server takes the place in second.
To synthesize.. i have to test the update process before to apply it on a production server..
My many concern are:
the php 5.4 intalled from remi repo still function after the double update?
how many time can take the update?
the data in the shared folder may be lost during the update ?
if the update fail can i restore the last backup made from the previous version of the os ?
But now.. how can i install phpmyadmin module from @dz00te repo ?
