Packages are collections of MBOs that are related by application use and authorship and grouped according to maintenance or distribution. Packages are initially created by developers, but are deployed and maintained on a production Unwired Server by administrators.
Administrators cannot change the name of a package if one has been defined by the development team. You can, however, create new package versions when you make an upwardly incompatible change to an existing application. In this case, leave both versions of the package running until every one of the remote client applications has been upgraded to the latest version; only then should you delete the old package version.
