Merge Multiple Campaigns Together For Enhanced Campaigns Migration

UPDATE 2013-04-14: Check Merge Labels from Multiple Campaigns for some help on merging labels.

Everyone is getting ready for Enhanced Campaigns and for a lot of people, that means finding an easy way to merge multiple campaigns into a single campaign. You may have a campaign for desktop traffic and one for tablet, or maybe one for each major mobile platform.

Well the beauty and the pain of Enhanced Campaigns is that you can do more with less. I haven't found a great way to easily merge multiple campaigns into one, so I made my own. All you need to do is specify a destination campaign where you want all the keywords, adgroups, and ads to end up and the set of campaigns you want to copy from. This script will pause any keyword and ad it manages to move over so you can see results and make sure everything is set up properly before deleting the old campaigns.

Thanks,
Russ
