Hi Zach, You will be able to maintain the location extensions once the existing GMB account is linked with the AdWords account and the filters are created in the GMB account. With these filters you can set the location extensions at the AdGroup level or the Campaign level. Please check this <https://developers.google.com/adwords/api/docs/guides/feed-services-locations#filtering_location_extensions> guide for more details. On the other hand, without the GMB account being linked, you will not be able to manage the location extensions. You could either request the client to link that GMB account or grant you access to their GMB account.
If the manual location extensions exist in the given AdWords account, it will be tagged for the auto migration. For each unmigrated location in the client Account, the auto migration will create a new unverified business location <https://support.google.com/business/answer/3480862> in a newly created Business Account (for the lowest level Manger account) and label it <https://support.google.com/business/answer/3370250?hl=en#labels> with its AdWords Customer ID. The original manually created feed items <https://developers.google.com/adwords/api/docs/reference/latest/FeedItemService.FeedItem> representing that location in AdWords will be removed. Please check this <http://googleadsdeveloper.blogspot.com/search?q=auto+migration> blog for more details about the auto migration.
