ArangoDB modify collection properties (keyOptions)

I have arangoDB already running with some collections filled with documents. I let arangoDB set up the _key for each document (traditional type).

I just found out that there is another type of setting up the _key, so called incremental type, which for me would be a high improvement of the DB as the _key values I am getting now are too long.

I know I can modify properties for already existing collections (see ArangoDB documentation). However when I try to modify keyOptions (see code below), keyOptions remains as type "traditional". 

curl -X PUT --data-binary @- --dump - http://localhost:8529/_db/mydb/_api/collection/companies/properties <<EOF
{
    "keyOptions": {"increment": 1, "type": "autoincrement"}
}
EOF

In ArangoDB documentation they specify: Note: some other collection properties, such as type, isVolatile, numberOfShards or shardKeys cannot be changed once a collection is created.

So I understand that keyOptions should be able to be modified.

The only attributes of a collection that you can change are waitForSync and journalSize. That is also what the documentation says.

The note (Note: some other collection properties, such as type, isVolatile, numberOfShards or shardKeys cannot be changed once a collection is created.) in the documentation is a little misleading. It only list a few examples of non modifiable attributes.

In summary: keyOptions is not be able to modify.
