Upgrade takes time due to Fix Script glidefix_deprecated_oncall_wf_plugin_install.xml activating deprecated On‑Call Workflow plugin<!-- /*NS Branding Styles*/ --> .ns-kb-css-body-editor-container { p { font-size: 12pt; font-family: Lato; color: var(--now-color--text-primary, #000000); } span { font-size: 12pt; font-family: Lato; color: var(--now-color--text-primary, #000000); } h2 { font-size: 24pt; font-family: Lato; color: var(--now-color--text-primary, black); } h3 { font-size: 18pt; font-family: Lato; color: var(--now-color--text-primary, black); } h4 { font-size: 14pt; font-family: Lato; color: var(--now-color--text-primary, black); } a { font-size: 12pt; font-family: Lato; color: var(--now-color--link-primary, #00718F); } a:hover { font-size: 12pt; color: var(--now-color--link-primary, #024F69); } a:target { font-size: 12pt; color: var(--now-color--link-primary, #032D42); } a:visited { font-size: 12pt; color: var(--now-color--link-primary, #00718f); } ul { font-size: 12pt; font-family: Lato; } li { font-size: 12pt; font-family: Lato; } img { display: ; max-width: ; width: ; height: ; } } During an upgrade from XP9a to ZP0, customers may observe that the upgrade process pauses or appears slow for approximately 11 minutes while executing the fix script glidefix_deprecated_oncall_wf_plugin_install.xml. This behavior is expected and does not indicate a failure or performance issue with the upgrade. The fix script performs the following action: Activates the deprecated On‑Call Workflow plugin for upgrade customers to ensure backward compatibility. The deprecated On‑Call Workflow plugin is required for customers who are upgrading from earlier releases and still rely on legacy workflow‑based On‑Call functionality provided by the On‑Call Scheduling plugin (com.snc.on_call_rotation).
