52 minuti fa, Thomahawk dice:unfortunate no one gave a complete step by step for manual upgrade without 1-click-upgrade, because 1-click fails every time, stuck at "now upgrading database..."
@Thomahawk
there is no step by step guide to do these jobs, you need knowledge of prestashop, you need knowledge of php, you need knowledge of databases and you need to be able to solve every problem that arises
If you are not capable of doing all this, it is better not to start updating work but to rely on a professional.
This scheme applies to any manual "professional" upgrade without using the 1-click-upgrade module
steps
1) install the new 8.x version from scratch with default theme and default modules.
2) you have to take the site you need to update offline, because you need the database to be stopped
3) take table by table and compare them properly and see if they are identical or if something changes, if something changes you have to align the table of the old version with that of 8.x.
4) after you have aligned the table of the old version, export the data and then load them into the 8.x table
5) repeat the same process for all tables
6) needless to say that you have to do very scrupulous work on the tables because if you make mistakes you will only have wasted time.
7) when you have finished with all the tables you will have the new 8.x site working with all the data.
8.) now you can install the updated modules for 8.x and the theme for the 8.x version
that's all
Good work
