Q: How does viewLinc upgrade my data for use in viewLinc
4.3?
A: viewLinc automatically detects your existing version and converts
your data. This is done transparently when you install viewLinc 4.3.
The data is treated as follows:
1 New top-level Zones are created based on the Zone structure
you set up in the earlier version. In addition, a top-level Zone
called ‘Unassigned’ is created for any unassigned Zones.
2 Locations are created for all active Channels. The Location name
is copied from the Channel’s preferred description (the
assigned Alias or Device description, depending on the system
preference). Duplicate Channels assigned to multiple Zones are
ignored.
3 If the earlier version of viewLinc has restricted Users con-
figured, viewLinc 4.3 Access Control permissions are applied,
according to the following procedure:
a All Users are assigned to the Group Everyone
b The Group Everyone is assigned View permissions on the
top-level Zone, without inheriting any permissions.
c Restricted Users: If previously authorized access to a Zone,
have their historical permission level automatically
assigned; If previously authorized access to a Channel,
have their historical permission level automatically
assigned.
d Users are assigned to Groups according to their historical
permissions.
e Regular Users: Automatically assigned access permission
allowing them to acknowledge alarms.
f Operators: Automatically assigned access permission allow-
ing them to configure Thresholds.
g Supervisors: Automatically assigned access permission
allowing them to configure alarms.
