change a_storage_type without moving content from filestore
I want to separate files in documentum by years,
Imagine that for year 2014 I create filestore fs_2014, for year 2015 fs_2015 and so on...
Now when I create my custom_type and set it default storage to fs_2014 all documents will be stored here. But in year 2015, I want to save all documents to fs_2015 so I will change custom_type default storage to fs_2015.
It's ok for new documents.
But when I want to append some content to documents which were created in 2014, all that data will go to fs_2014 not to fs_2015.
When I change a_storage_type on fs_2014 documents to fs_2015 - all data will migrate to fs_2015.
So my question is how to achieve this and have content separate in filestores for one sysobject?
I know, that when I change a_storage_type only through database all works ok for me, but I don't know till when
