My previous programmer used version 3.4 to develop our backend tool. Now we want to upgrade to version 4.6 but he left.
Could you please advise me on this? I’m not a good web programmer, sorry.
To upgrade from v3.4 to v4.6 you will need to reintegrate the v4.6 from scratch. If you are not experienced developer then you should hide a developer who can accomplish this task. There are a lot of changes between v3.4 and v4.6 so you can not simply replace the folder and code. You will need to reintegrate the entire theme from scratch.
If you need any further clarifications please let us know.
