What's the expected process to move a RavenFS database from 3.5 (or 3.0) into 4.0?

[Bruno Lopes]

Doing a "Import data from a .ravendbdump file into the current database" to load a .ravenfsdump fails with "The archive entry was compressed using an unsupported compression method."

[Oren Eini (Ayende Rahien)]

That _should_ work.

How did you create the ravendbdump file?

Other methods include pointing to a live instance and getting all the data from there directly, creating a new db from an existing 3.5 db, etc.

Exported a file store from a 3.0 instance.

Pointing to a existing server is a bit harder, since in this case I want to restore locally an instance that's remote

Importing the export should work, IIRC

[Bruno Lopes]

Here's what I did:
- created a fs on 3.5 build 35246.
- on the fs, created two folders, uploaded two zip files
- exported the fs

on 4, build 4.0.0-rc-40025, tried to import the file, and failed. Stack trace on the bottom, and ravenfsdump attached.

The archive entry was compressed using an unsupported compression method.

Hi Bruno,

In order to import RavenFS to RavenDB v4.0, you'll need a live instance of RavenDB v3.x with a file system.

You can import it in the Import Database -> From another RavenDB server tab.

Make sure to select Import RavenFS

Ah, it's not working on the RC, but it works on today's nightly.

Quick note: the filesystem doesn't appear on the dropdown list for "database name". It works if I specify the filesystem name, but at first I thought it was bugged (as it showed the databases)

Also, I had to only select RavenFS. I tried with the other options toggled and it failed with:

[23:00:29 INFO] Strated processing RavenFS files
[23:00:33 INFO] Read 9 RavenFS files.

All issues are fixed and will be in the next build.
