Unable to upgrade to V7.12.6 - Error 408 Request Timeout

Hello,

I would need to upgrade 7.12.5 to 7.12.6

Is the wizard a good choice to do it or there are possible issues/missing?

Once I wrote a post with some steps to help clarify/simplify the upgrade process for the 8 version,
but never received a full confirmation of its goodness. Then I switched back using the 7.12.5 version .

Now if the upgrade wizard is not reliable maybe those steps are applicable in this case?

Thanks
Mario
