Migrating Your Presto Artifacts to Presto 3.0

Presto 3.0 has a new migration utility to simplify the process of moving and updating your services, mashups and Mashlets to 3.0 mashables, mashups and Apps. Migration moves and, as needed, updates all your Presto artifacts to compatible formats for 3.0. Migration also moves any meta-data you have defined, such as providers, categories, and optionally users and groups, to this new release.

Note: you must migrate from Presto 2.7.0 to 3.0. If you are still working with an earlier release, you must migrate to 2.7.0 and then migrate to 3.0.

To get started:

  1. First, download the Migration Utility (~81K) and save the Zip file in any folder on the computer where you have installed Presto 3.0.

  2. Extract the contents of the Zip file that you downloaded to this existing folder:

    presto-install-folder/prestocli

    On Windows, this is typically C:\Presto3.0\prestocli. On UNIX platforms, this is typically /user/myhome/presto3.0/prestocli

    The Migration Utility download installs or updates the following files in your Presto 3.0 installation:

          -> presto-install-folder/prestocli (Presto command line interface files and scripts)
            -> README-migration.html (this README file)
            -> bin/migrate.sh
            -> bin/migrate.bat
            -> dist/prestocli.jar (Updated migration utility)

  3. Next, start your preparations and begin migrating. For migration instructions, examples and solutions to common issues with migration, please see Migrating to New Versions in the Presto Library.
