> h2. Use Cases
> * User starts up and activates brand-new grid. On activation BaselineTopology
> is created and persisted.
> * User starts up some (not all) nodes of old grid (BLT might be already
> presented on them) and activates new smaller grid.
> BLT is recreated with fewer number of nodes and replaces previous BLT in
> persistent storage.
> * User starts nodes of old grid (each node already has a BLT available
> locally). When all nodes presented in BLT are started grid is activated
> automatically.
