MailStream Plus on IBMi - library backups recommendations before installing a new version

Product affected: MailStream Plus™, all versions  
Operating System: IBMi (AS400, iSeries)
Before starting the installation process, you should back up the functions library (G1@@PGMS) and the product library (G1MSPGMS), or wherever the xx@@PGMS Global library and the MailStream Plus™ xxMSPGMS library are installed on the system.

------------------------------------------------
Because jobs may be 'forwarded' from working with the the old MailStream Plus (MSP) version to be able work with the new MSP version, in case for any reason you might need to revert to the previous version, you might also wish to back up the Work Library(ies) as shown on the 'Work with Jobs' screen shown below
