yes i done it again 
may be it helps some one upgrading from old versions, i have upgraded this system several times from 4.2, i am doing it on dev server so some of the files not up to date
* get a copy of all documentlibrary from live to dev
* re-index from server admin
* i got a latest bundle liferay-portal-6.1-ee-ga3-sp1, prev i am doing on liferay-portal-6.1.30-ee-ga3
*migration removed dl.hook.impl, set properties dl.store to FileSystemStore
* while doing indexing several times to make it error free , need to cleanup some of the journal,wiki,software catalog ,image rows from database where group not exist in group table, it is happened because this system upgraded from old system when we delete community seems not deleted data related to that group from some tables

Note: you need to take / should have a backups because we need to put them back and try until we have success( Others say in forum wash,rinse & dry ) ..
every time if it is not successful then you need to restore database with 6.0.12 and try with different settings
when i done i have in portal-ext for upgrade as i have the following so check as per your settings
# note this in 6.0.12 i have migrated to DLHook Since 6.1, only DLHook is supported.
#changed as per your directory
liferay.home= /opt/liferay-portal-6.1-ee-ga3-sp4
resource.repositories.root= /opt/liferay-portal-6.1-ee-ga3-sp4/data
image.hook.impl=com.liferay.portal.image.DLHook
image.hook.file.system.root.dir=${liferay.home}/data/images
#
# FileSystemStore
#
dl.store.impl=com.liferay.portlet.documentlibrary.store.FileSystemStore
dl.store.file.system.root.dir=${liferay.home}/data/document_library
hope this helps

Thanks for your prompt reply.
I already create Database dump for it and restore countless time when upgrade failed...
From my previous portal-ext i only add these attribute: (maybe need to add more attribute)
-By default "image.hook.impl=com.liferay.portal.image.FileSystemHook" is the attribute for migration. So i need to change it to "image.hook.impl=com.liferay.portal.image.DLHook" so that v6.1 will be supported.
-Do i need to configure something for "DLHook" in webpage before migration happen? (Sorry for asking so much question, im still new to this liferay.
)
Btw,I will give it a try using your configuration provided. Thanks you very much.... ^_^
