Versions of Iguana prior to version 4.5 enabled you to organize users into user groups. In version 4.5 of Iguana, roles are provided in place of user groups. When you upgrade to version 4.5, the following conversions are performed:

• When you upgrade to version 4.5, all user groups that you have created are automatically converted to roles, and all members of a user group automatically become members of the corresponding role. Any permissions that a user was granted in previous versions of Iguana are granted in version 4.5.
• A channel group named All Channels is created. This channel group contains all Iguana channels, and the group cannot be edited.
• If a user group has administrative permissions, its corresponding role has Edit and Start/Stop permissions on the All Channels channel group.
• Users in user groups with administrative permissions are also automatically added to the Administrators role, and therefore have full access to the Iguana server.
• If a user group had permission to export logs, the corresponding role in version 4.5 is given Export permissions on the All Channels channel group.

In addition, the following transformations are used if your Iguana server uses any of the default role or channel group names that are defined in Iguana 4.5:

• If you have created a channel group named All Channels, it is automatically added to the Iguana 4.5 server.
• If a user group is named Administrators (or any similar case-insensitive equivalent, such as administrators or ADMINISTRATORS), it is renamed Old Administrators Role (with its capitalization preserved). Email notification rules that referenced Administrators will reference Old Administrators Role in version 4.5.
• If a user group is named Users (or any similar case-insensitive equivalent, such as users or USERS), it is renamed Old Users Role (with its capitalization preserved). Email notification rules that referenced Users will reference Old Users Role in version 4.5.
