[orion-dev] The default is now the new simple meta storage format

[Anthony Hunter <anthonyh@xxxxxxxxxx>]

Hi Team,

I have delivered the changes to master,
see https://bugs.eclipse.org/bugs/show_bug.cgi?id=421024

In Orion 5.0, the default is now the
simple metadata storage.

If you start Orion with a new server
workspace, the simple metadata storage is used.

If you start Orion with an existing
workspace, an error message that the existing legacy metadata storage exists,
a pointer to the migration wiki document is given and the legacy metadata
storage with the existing files is used.

We do not do automatic migration, since
that would modify the project folders on disk without the administrator's
knowledge. You may give permission that a migration can occur to the new
simple format by setting orion.core.metastore=simple (just like in Orion
4.0).

Migration and storage details are in
https://wiki.eclipse.org/Orion/Metadata_migration#Orion_4.0_Migration

Cheers...
Anthony
