hi, This script will check this error.

can I upgrade?

thanks

After you have converted your database to UTF8, yes.

what use? utf8mb4 or uff8?

utf8mb4 – otherwise you can’t use most of the emoji symbols for example. 

And if you do choose to go with UTF8, you can convert the database to UTF8MB4 at a later point after the IPS upgrade, via an option in the ACP.

what choice do I have to choose? what does it include converters?

Converters are files to change (convert) other software databases and files for use with IPS. If you're upgrading from IPS to IPS, you don't need them.
