Update xibo, v1.7.4 >> 1.7.6

I will wish to perform the update xibo.
I’m on mac and I have to access the server sftp.
Xiba has been installed on a Windows machine.
how do I proceed?
I have already made a backup of the database directly from the xibo management interface.
Apparently it is advisable to clone the database.
I have to make the command line procedure.
Can you tell me how?

Thanks for your help.

Hi,

Did you have a look here?:

Hi Peter,

Thank you for your answer.
Yes I have read it, but I would like to know if its really necessary to clone database.
I saved my database by management interface, and I would like to know if its enough or if I really need to clone it too.
Also what’s the command line to access to xibo machine, to install new version?
