UPGRADING.mysql Error

Following the documentation…
https://docs.bestpractical.com/rt/5.0.0/UPGRADING.mysql.html

I ran the command changing the db name, user & password:

perl etc/upgrade/upgrade-mysql-schema.pl db user pass > queries.sql

It worked but the import failed…

[root@rt ~/rt-5.0.1] # mysql -u root -p rt5 < queries.sql
Enter password:
ERROR 1283 (HY000) at line 11: Column ‘Content’ cannot be part of FULLTEXT index

So I ran each command one by one… This is the culprit:

mysql> ALTER TABLE Attachments MODIFY Content LONGBLOB NULL DEFAULT NULL;
ERROR 1283 (HY000): Column 'Content' cannot be part of FULLTEXT index

Any suggestions? Can this be safely ignored for now?
