Usage

To export data from Papermerge 2.0:

create source.yaml file

version: 2.0
media_root: /path/to/media/folder/
database_url: /path/to/data/papermerge.db

Run following command:

$ pmdump -c source.yaml -f pm2.0.tar.gz export

It will create pm2.0.tar.gz archive.

Create dest.yaml file

version: 3.4
media_root: /path/to/media/folder/
database_url: /path/to/data/papermerge.db

$ pmdump -c dest.yaml -f /path/to/archive.tar.gz import

Note that export or import commands are at the end of parameters list.

You need golang version 1.24:

$ go version

go version go1.24.0

To compile from source code use following commands:

$ go mod download
$ go mod tidy
$ go build dump.go

Above commands will create pmdump binary.
