Before you go into production with Zend Server 2020, test everything. Test until you are sure everything works. Test until you know everything works. Test until you know that you know that everything works. If you have never built any kind of test plan to exercise your entire site, now would be an excellent time to do that. This article is just a guide to the most common considerations for the migration. We can't think of everything. The only way to be sure you have taken care of everything is to verify that you have taken care of everything. Test it all.
Set Start up Entries
When you are ready to go live with version 2020, you will want to stop earlier versions from starting automatically whenever you restart your IBM i. You will also want to have version 2020 start automatically.
For Zend Server 8 and earlier, use this command to prevent automatic start up:
RMVAJE SBSD(QSYSWRK) JOB(ZS_STR_SBS)
For Zend Server 9, 2018 or 2019, use this command to prevent automatic start up:
RMVAJE SBSD(QSYSWRK) JOB(ZS9_STRSBS)
To set Zend Server 2020 to automatically start up:
GO ZENDPHP74/ZSMAINT
Use option "20. Zend Server Subsystem action at IPL". Use F10 to set it to automatically start at IPL. If it is already set to start at IPL, F10 will not be available.
