All You Need to Know About ServiceNow Upgrade

Outline the upgrade preparation for ServiceNow, detailing the upgrade planning checklist, seven phases, dev instance prep, cloning concepts with data preservers and exclude tables, and essential upgrade documents.

Master the seven-phase upgrade plan for ServiceNow, from release notes through dev, test, and prod upgrades, including 51 checklist tasks, validation, and user acceptance testing.

Navigate the upgrade planning checklist and master the Vancouver release notes, including features and changes by product, release note summaries, and pre and post upgrade tasks.

Review pre and post upgrade tasks in the upgrade planning checklist, identify modules needing manual task-table reindexing, and verify mid server and JRE prerequisites for Vancouver upgrades.

Phase two covers planning the upgrade and preparing the dev instance, defining which instances are in scope, and sequencing upgrades from dev to test to prod.

Master cloning by copying full data from prod to dev, wiping the target instance. Discover how excludes tables and data preservers control what gets copied or preserved during a clone.

Document the upgrade with a project plan, release notes analysis, test cases, and a defect tracker to manage defects, update sets, runbook steps, and a 51-item upgrade checklist.

Explore the execution phase of the ServiceNow upgrade, detailing dev instance upgrades, validating in dev, script locks, other instance upgrades, and prep for the production upgrade through final prod upgrade.

Upgrade the dev instance via the high portal, then validate with skip log analysis, run the test plan, and capture any defects in update sets.

Uncover how skipped logs arise during a ServiceNow upgrade when local updates to out-of-the-box items collide with the target version, illustrated by update sets, dictionary labels, and form layout changes.

Choose actions for upgrade skipped blocks, such as reviewed and reverted, retained, merged, or not reviewed. Apply similar decisions for update sets with accept or skip.

Phase five guides upgrading non-prod ServiceNow instances by cloning from prod and upgrading test/qa/uat environments, installing plugins and custom apps, skipping log analysis, and validating with test scripts.

Coordinate phase six readiness and phase seven production upgrade by securing sign-offs, approvals, and change advisory board communication, then monitor, apply update sets, validate, and inform stakeholders.

Perform a hands-on upgrade on a developer instance, monitor the upgrade process, and understand how the node gets upgraded, including handling skipped blocks and proactive measures for the skip logs.

Prepare a developer ServiceNow instance for the Vancouver upgrade by modifying two business rules and one script include to enable skip logs and reveal versions before upgrading.

Upgrade a personal developer instance (PDI) via the developer portal, selecting Vancouver patch two, and monitor progress with upgrade center and script-block previews across four phases.

Resolve skipped blocks in the ServiceNow upgrade by reviewing skip changes, resolving conflicts, and choosing retain, merge, or revert actions to finalize upgraded script includes and business rules.

Proactively manage skipped blocks by reviewing upgrade history, checking out-of-the-box items touched but not upgraded, and resolving conflicts to reduce future upgrade skips.

Learn to upgrade ServiceNow efficiently by avoiding changes to out-of-the-box items to prevent script lock, create new rules or script includes, and follow a dev-to-prod upgrade plan.
