I have created the schema with Workbench 6.1 (and MySQL 5.6) and it outputs the code below. But this produces a foreign key constraint. Last time it worked but produced a composite primary key made of the other foreign keys which is overkill I think.
Does anyone have an idea what is wrong here?

I am transferring a single table from MySQL 5.7 to MySQL 8.
First, I used mysqldump db_name table_name > table_name.sql in my current server(MYSQL 5.7); taken from here
Then, in my VM with MySQL 8, I used mysql -u username -p db_name < /path/to/table_name.sql.
The columns with the 'blob' data type are not correct, the other columns are okay.
the 'blob' columns went from "International Master (1973); Grandmaster (1975); FIDE Senior Trainer (2004).Alexander Genrikhovich Beliavsky was..." to "0x3C703E496E7465726E6174696F6E616C204D6173746572202831393733293B204772616E646D617374657220...".
Both databases have character-set = latin1 and collation = latin1_swedish_ci.
How can I properly transfer the 'blob' columns from MySQL 5.7 to MySQL 8?

explain of the query
which ones have index
it looks you need composite index because file sorting.
usage:
CREATE INDEX index_name
ON table_name(c2,c3,c4);
You are getting above result because some time o/p of explain gives different result as response of query of prod.
For optimization of query you can't have a fix answer. it varies from case to case. As for this situation I think you need to perform performance testing of this query. You can do this by inserting some records in all referenced table and then checking it's performance using explain.
LEFT JOIN campaign_in_category c6 ON c.id = c6.campaign_id
seems to be totally useless. But the Optimizer may not realize it. Remove it and any other dead code.
I am trying to migrate my osclass installation to another server. I have copied all files and created a new database. When trying to import my database from backup, I get "#1215 - Cannot add foreign key constraint".

Please help.
You must create first the tables you want to reference, for example, here is one foreing key that reference one table, also the type of the key must match, follow this example an add the rest of your tables, I will show a minimum example that works in the creation of the tables, you must add the correct data of course:

I get #1215 - Cannot add foreign key constraint , error in mysql tried adding foreign keys after creating table but it still gives the same error. I don't know what I'm doing wrong here.
First of all Check whether you have applied indexes on the keys.
As per your code their is no point in referencing id,UserName and Email.
Only id is enough for referencing.
Check the following code
CREATE TABLE IF NOT EXISTS `lawncare_message` (
`ID` int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
`Reason` int(5) NOT NULL,
`Subject` text NOT NULL,
`Description` text NOT NULL,

`CustomerEmail` varchar(255) NOT NULL,
`SendTo` int(11) NOT NULL,
`SendToUser` varchar(255) NOT NULL,
`SendToEmail` varchar(255) NOT NULL,
`Status` int(5) NOT NULL DEFAULT '0',
`AddedBy` int(11) NOT NULL,
`AddedOn` date NOT NULL,
FOREIGN KEY (SendTo)
REFERENCES lawncare_user(ID)
ON UPDATE CASCADE ,
FOREIGN KEY (Customer)
REFERENCES lawncare_customer(ID)
ON UPDATE CASCADE
