Multiserver backup to 3.0.5.1

[beenfishing]

Hi

I am busy trying to upgrade my production multiserver setup from version 3.0.4.6 to vesrion 3.0.5.1.

I have started with one of the slave server but I am getting this error, is it normal? Should I carry on upgrading the other slaves and them the master?

Reconfigure Permissions in master database? (yes,no) [no]: yes
