Hi All,

Right now , i am encountering a problem that there is one dummy blob id which is trying to be migrated but throwing an exception.I think, this BLOB id is of DummyBlobStore.

Is there a way to exclude these blob store while doing the migration?

    I am able to successfully migrate the content by running below command.

    java -jar crx2oak-1.8.4-all-in-one.jar segment-old:C:/Users/xxxx/Documents/xxxx/Softwares/AEM/Chris/AEM_Author_60/crx-quickstart/repository C:/Users/xxxxxx/Documents/xxxx/Softwares/AEM/6.4/crx-quickstart/repository --datastore C:/Users/xxxx/Documents/xxxx/Softwares/AEM/6.4/crx-quickstart/repository/datastore --include-path=/content --exclude-path=/tmp --copy-versions=false --copy-orphaned-versions=false > migration_new.txt

    Thank you all for your support.

    I have asked others to look here as well.

    In mean time - have you gone through all the AEM migrations Docs?

    Hi Kishore,

    Looks like you are doing a repository migration. What is the source version and what is the target version? What command line are you using for this call?

    regards,

    Jörg

    Hi Kishore,

    For me it looks like you used an blobstore on your AEM 6.2 instance; can you experiment with the parameters "src-fileblobstore" and "fileblobstore"?

    i don't see any blobstore folder in my source repository(6.2).Not sure, how to use parameters "src-fileblobstore" and "fileblobstore" in this case?

    Is there any chance to have implicit blobstore, comes up with the AEM installation?

    These parameters are discussed in this doc -- Using the CRX2Oak Migration Tool

    i see below message in the logs.

    I doubt it ,implicit blobstore comes up with the when installing AEM.

    " 26.04.2018 18:18:29.818 INFO   o.a.j.o.u.c.p.DatastoreArguments: Destination blob store: DummyBlobStore ".

    Right now,i have only two folders inside /crx-quickstart/repository
