Images and document not visible after migration to liferay 6.1.0 GA1 - liferay-6

Question

I upgrade from liferay 5.2.3 to 6.0.6 , it was successfully done without any error left; but when I upgrade from 6.0.6 to 6.1.0 GA1, unable to see the images and documents.
Steps related to images and documents I have done during migration(only related to documents are described).
during migration to 6.0.6 I wrote following lines to my portal-ext.prropeties file
image.hook.impl=com.liferay.portal.image.FileSystemHook
image.hook.file.system.root.dir=${liferay.home}/data/images
dl.hook.impl=com.liferay.documentlibrary.util.FileSystemHook
dl.hook.file.system.root.dir=${liferay.home}/data/document_library
I know in liferay 5.2.3 we have saved the images and documents to file system.
after this I start the server and migrated legacy permission to 6. It was successful , I was able to see the documents and images.
Now it turn to migrate from 6.0.6 to 6.1.0 GA1 , for that I wrote in these lines
image.hook.impl=com.liferay.portal.image.FileSystemHook
image.hook.file.system.root.dir=${liferay.home}/data/images
dl.hook.impl=com.liferay.documentlibrary.util.FileSystemHook
dl.hook.file.system.root.dir=${liferay.home}/data/document_library
start tomcat, migrate permissions to 6, after successful migration , re start the server but unable to see the documents and images. when ever trying to access the file in contents getting this error in tomcat console
Current URL /c/document_library/get_file?uuid=be4eecc7-8e9a-416c-aa4d-f3cbd855d759&groupId=14 generates exception: No file versions found for fileEntryId 61901

can any one suggest what I am missing ?

Answer 1

image.hook.impl=com.liferay.portal.image.FileSystemHook
image.hook.file.system.root.dir=${liferay.home}/data/images
dl.hook.impl=com.liferay.documentlibrary.util.FileSystemHook
dl.hook.file.system.root.dir=${liferay.home}/data/document_library
is for telling liferay 6.1 from where to migrate documents and images
and to tell where to migrate them to you need to use new properties (this is what you were missing)
dl.store.impl=com.liferay.portlet.documentlibrary.store.FileSystemStore
dl.store.file.system.root.dir=/path/to/liferay6.1/document_library
Upgrade process will copy images and documents to new location (dl.store.file.system.root.dir) so be sure not to have same values for dl.hook.file.system.root.dir and dl.store.file.system.root.dir
EDIT
Above is for 6.1 EE.
For CE version only images should stay in original location and documents must manualy be moved/copied to new location.
