[opensuse] What happens if I rerun the vendor change?

I ran '$sudo zypper dup --from packman-essentials --allow-vendor-change' after adding 'packman' repository. But, the network issue occurred, so I 'ctrl-c'ed and then re-ran the command after fixing my internet. But what happens if I re-rerun that command without '--from' option? I mean just '$sudo zypper dup --allow-vendor-change'? Will it come to the main repository again or no-effect?
