Moves a list of remote media from one media store to another.
|
|
|
|
The input should be a list of media files to be moved, one per line. Each line
|
|
should be formatted::
|
|
|
|
<origin server>|<file id>
|
|
|
|
This can be extracted from postgres with::
|
|
|
|
psql --tuples-only -A -c "select media_origin, filesystem_id from
|
|
matrix.remote_media_cache where ..."
|
|
|
|
To use, pipe the above into::
|
|
|
|
PYTHON_PATH=. ./scripts/move_remote_media_to_new_store.py <source repo> <dest repo>
