The endpoint is the following:
POST /storage_service/vnode_tablet_migrations/node/storage_mode?intended_mode={tablets,vnodes}
This endpoint is part of the vnodes-to-tablets migration process and
controls a node's intended_storage_mode in system.topology. The storage
mode represents the node-local data distribution model, i.e., how data
are organized across shards. The node will apply the intended storage
mode to migrating tables upon next restart by resharding their SSTables
(either on vnode boundaries if intended_mode=tablets, or with the static
sharder if intended_mode=vnodes).
Note that this endpoint controls the intended_storage_mode of the local
node only. This has the nice benefit that once the API call returns, the
change has not only been committed to group0 but also applied to the
local node's state machine. This guarantees that the change is part of
the node's local copy upon next restart; no additional read barrier is
needed.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
