Virgo/Community/Migrating from slices
Migrating from the dm Server slices prototype to the Virgo snaps prototype
Even though the slices project was a prototype, a number of dm Server users found it very useful and asked for it to be made available on Virgo. It is currently being renamed to "snaps" and contributed to Virgo.
There will be a one-time hit for users to migrate from slices to snaps, largely because of the renaming.
Samples
