As you are planning the day of the upgrade, be sure to contact your billing vendor to 
make arrangements to suspend the billing interface on the night of the upgrade. This 
is an important step in the planning process to ensure that your system is not 
accessing the database during the upgrade process. In addition, contact the 
provider(s) of any third-party applications that your system supports. Follow their 
guidance in determining whether these third-party interfaces should be stopped and 
if the application needs to be updated during the upgrade.  

 

To save valuable time, complete the following procedures in this chapter prior to the 
beginning of the maintenance window. Depending upon the size of the system you 
are upgrading, it should take about 3 or 4 hours to complete these procedures.
