Error to migrate from version 1.6.1.20 a 1.7.7.4

[el_brujo]

Hello friends, I am trying to migrate from version 1.6.1.20 to 1.7.7.4 with the 1 click module, I have several errors but I already tried several things after reading a lot, I detail

1) When trying to enter the admin, I entered the username and password and after clicking to log in, only the prestashop logo remained, frozen,

Solution: change the php version from 7.3 to 7.4 -> in this way, log in, but I have a new

error: Deprecated: array_key_exists (): Using array_key_exists () on objects is deprecated. Use isset () or property_exists () instead in /home1/mlaislaciones/public_html/src/Adapter/EntityMapper.php on line 99

2) The solution that is presented in this forum is to change to php 7.2, in the first place I do not have that possibility, but in an alternative server that if I have I tried it and I return to the first error of freezing the login.

Did it happen to someone? regards!

Forget PHP 7.4. It is not supported at the moment.

I don't know about your frozen logo error. You should look for error messages or warnings.
