mySQL patch 1.8.13 > 2.0 table already exists

[HullZabbix]

From within the /upgrades/dbpatches/2.0/mysql folder I've run the following

./upgrade zabbix -u username -p

After running for around 20 minutes it comes back with the following error:

error 1050 (42s01) at line 171: table 'globalvars' already exists

I've searched for previous thread and found that someone had a similar problems going from 1.6>1.8

For the time being I've reverted to a backup. But next time I try does anyone have any idea how to get around this?

e.g.
DROP TABLE IF EXISTS `globalvars`;
then stop mysql service. Remove globalvars.frm /var/lib/myql/zabbix

Any comments?

Just to put an end to this,

I created a new virtual machine, put CentOS + mysql on there and imported the db, then performed the upgrade, which completed OK. Then imported it in to the zabbix server, so all is well.
