space for migration from DOCman

I am considering migrating content from DOCman. Those documents are roughly 35 gigs of space, and I plan to have eDocman set up to use S3 before the migration. My concern is whether I need another 35 gigs of disk space during the migration process. I can see the migration process as just reading files from Docman and then loading them to S3 - thus not needing to store those documents a second time. Or, I can see the migration copying the files to a new location and in a process later upload them to S3 - thus requiring I have up to another 35 gig of free space.

So if I migrate from DOCman into eDocman which is using S3, will I need any extra disk space during this process?

Hi,
The migration tool will only work when you store documents (of DOCman) in the same hosting with Edocman, and we can't use third party storage (like S3) in this case. Because Edocman will not able to move physical files of Docman to S3 storage

Let me clarify to make sure we are both understanding the same thing...

Currently the documents are on the same server, but managed by DOCman. When we conduct the import, does eDocman make copies of these files for use by eDocman? Are you saying that S3 storage occurs only after all the documents have been migrated?

The thing I want to know is whether or not I need an additional 35 gig of space to conduct the migration.
