Upgrade from EE2 to EE3

Hi

Due to other commitments only getting to upgrade my site now and running into an error.

Exception Caught SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes: ALTER TABLE `exp_channel_titles` CHANGE `url_title` `url_title` char(200) C:/Users/scott/OneDrive/MAMP/sites/nifootball.co.uk/_site/system/ee/legacy/database/drivers/mysqli/mysqli_connection.php:122 Stack Trace: hide details

I have upgraded to 2.11.9 first so my site is on the latest of that, I have disabled any modules/plugins that I don’t think are required. I have deleted a lot of older data that is not required and also run through the playa/matrix upgrade.

I start the upgrade and shortly after I get the above error, any assistance appreciated.
