Updating mysql 5.5 to 5.7

I am trying to update a database with multiple table from 5.5 to 5.7.

I create a backup of the Database and save it to my local machine

I create a new 5.7 DB on the ionos server.
When created I upload the backup to the newly created DB but get the following error message.
Any ideas how to overcome this very welcome!

Many thanks
John

delete the text:

phpMyAdmin SQL Dump

from that file. I'm not sure why it is there, but it isn't a valid SQL statement.

Thanks Ray
I made the change but kept getting more errors after the changes I made.
Finally I think I managed to get the update done via Navicat Dump SQL File
Seems to have created the new DB correctly.
Fingers crossed.

Seems like there is a bug problem on the remote server.

I'd have to look. It sounds like your export put in comments and the import is trying to run the comments as code. The solution might be a setting to either not include comments in the export or tell the import what the comment syntax is.

Please see PM

It looks like you hand coded that connection file and didn't use our webassist extension, so there is an error in it. I'd re-generate it with our extension, but the solution if you want to continue to use yours may be to just change mysql_error to mysqli_error on the line mentioned... but you could run into other issues down the line. The best bet is to use the webassist generated connection file instead of your own hand coded one.

The error you get is because the username and password is incorrect. Anytime you get "Authentication failed." it means that it is connecting to a database but the username and password aren't correct for getting data.

I have created a connection file for the remote server
It displays an error message and I am not sure which field this refers to.
Can you please indicate this. I hope it is not the password.
I am attaching an image.
Thank you
John

The connection name... the first field. It can't have .php in it (the file will be created with this name and .php will be added to the file name automatically)
