HRD Migration & Blob keys

[Phil McDonnell]

I'm looking at migrating to HRD and I use the blob store.  In my datastore I have one Kind of entity that stores a blob key as one of the fields in the Entity. I see that the HRD migration warns about blob keys stored in "serialized form." Pardon my ignorance, but are my blob keys that I mentioned stored in serialized form? Quotation from the documentation & example of my blob key in the Entity (highlighted yellow) below.

Thanks,

Phil

Warning from the HRD Migration:

If your application has blob data in Blobstore, you need to migrate that blob data as well. Check the checkbox labeled Migrate Blobstore Data. The blobs will be copied and given new blob keys in the new application, and the Datastore will be updated with the new blob keys. (However, any blob keys stored in serialized form within the Datastore will not be migrated; see Migrating Serialized Blob Keys, below, for more information.)

Example of my datastore from the datastore viewer:

	ID/Name	complete	couponKey	date	dealID	dealVariant	fraudulent	numSold	ppemail	price	purchase	sold	uid	verified	address1	address2	charity	city	fullname	state	zip
	id=174125	True	AMIfv95dj6WTPGjP8P38yQrSmjbPs6eqWCFpvafA0Y9KoROcostO8OiHMWOwZKFfqmNwfi2s9pXyK7Bz8cOIG-CSPnv-T9r0ac9Fn_c5carOHrpRBxFz-Pm3zcI4j93-MDHssxDpC6PdnKY5P3Dr66BrGLHWqoBNzQ View blob	2012-01-23 05:19:04.658000	asdf	0	False	1	as...@asdf.com	4.0	False	True	10709668	True	<missing>	<missing>	<missing>	<missing>	<missing>	<missing>	<missing>

Is anyone familiar with this blobstore issue in the HRD migration?

Think I've got it now. No need to reply here.

Hi Phil,

Can you please share how did you manage to fix it? We are experiencing the same issue. Currently, we are in Sync phase and none of our blobs have migrated to new HRD app. Do we need to run the blob migration manually before the final migration step?

Any help will be highly appreciated.

thanks!

We missed our blobs during the migration (as we weren't using Keys directly), so we had to write a RemoteAPI app that migrated them (read from old app I'd and create in new one) and update all DS references to them!
