Figure 20-2. Data Backup Screen - Migrate and Factory Reset
Migrate:
Loading data from an older version of the Vission 20/20
software to a newer one can be complicated due to dif-
ferences in databases. This migrate function closely
examines each fi eld in the database being loaded and
determines whether it can be used in the new program.
The Migrate function is executed automatically when a
data is loaded from a USB fl ash drive. The only time an
operator should have to use the following migrate but-
ton is if a new Vission 20/20 program is loaded over an
existing Flash card, see Figure 20-2. Data Backup Screen

Migrate:
• This button initiates the migrate function.
Factory Reset:
The Factory reset button offers the operator the ability
to reset all the Vission 20/20 setpoints back to the facto-
ry default settings or a specifi c database. If the operator
fi nds that a screen will not load when selected, it is likely
that the database associated with that screen has been
corrupted. Unfortunately, data corruption is always a
possibility in any system. So this function was designed
to help the operator to regain control, see Figure 20-2.
