ArticlesRetirement: Sencha Project Planner and Resource Planner

PSA

Why are Project Planner and Resource Planner being Retired?

• Project Planner and Resource Planner, both built using Sencha/EXTJS, are being retired primarily because Certinia is no longer developing within this framework
• Sencha development results in worse performance at scale compared to Lightning, and offers a less desirable customer UX than Lightning
• Additionally, Bryntum, a key component provider for Sencha, will no longer support it after December 2026, creating further risks
• The replacement, Work Planner, offers a modern Lightning-based experience with better performance and user interface

What is the impact of this replacement on users?

• Customers will need to transition their processes and potentially update configurations to utilize the Work Planner
• Certinia recognizes the scale of this impact and is planning a multi-year transition process to minimize disruption

What is replacing Project Planner and Resource Planner?

• Both Project Planner and Resource Planner are being replaced by the Work Planner
• The Work Planner is a Lightning-based component designed to offer improved performance, better user experience, and continued feature development
• Different initial filtering options within the Work Planner will cater to use cases previously addressed by separate Project Planner views (such as Full Page Work Planner, Resource Work Planner, and Project Manager Work Planner)

What is the timeline for the replacement of Project Planner and Resource Planner?

• The replacement for both Project Planner and Resource Planner was announced in Spring 2025
• The features will have replacement notices added to them in subsequent releases
• They are slated to be completely removed from the product package by the Winter 2027 release
• This multi-release timeline aims to provide customers with sufficient time to transition to the Work Planner

How should existing users transition to the Work Planner?

• Existing users can begin using the Work Planner in parallel with the Project Planner and Resource Planner by assigning users the appropriate permission set (PSA - edit work planner)
• To fully transition, users must remove permissions from the old planners and grant permissions for the Work Planner components
• Configurations like color coding is generally retained, but field set and custom setting-driven behaviors may require administrators to update lab options in the Work Planner
• Users may need to create new app pages for the Work Planner and restrict permissions accordingly

What specific feature from Project Planner will not be available in Work Planner initially?

• The ability to mass shift project dates from the Project Planner is not available in the Work Planner
• While there are considerations for handling this at scale potentially as an asynchronous job in the future, it will not be part of the initial Work Planner offering
• Work Planner will still meet most user needs without this feature initially
