K2 replacement planning

A practical K2 replacement path for workflows, forms, and business data

Every K2 capability has a first-class equivalent in UserTasks — SmartWorkflows, SmartForms, SmartObjects, worklists, rules, and roles are all natively covered — and UserTasks adds a modern platform on top: AI agents, an OAuth 2.0 provider, an MCP server, real-time kanban and messaging, and a fully open-source, free-forever on-premises option. Workflows and forms can even be built programmatically. Replacing K2 is an application modernization program, not a file conversion, so migration should preserve process intent while deliberately redesigning legacy coupling and exceptions.

01

Every K2 capability is covered — plus a modern platform on top

UserTasks meets the complete K2 SmartWorkflow, SmartForms, and SmartObjects capability set with first-class equivalents, then adds capabilities K2 never shipped. You are not trading features to modernize — you gain them.

  • Workflows, SmartForms, SmartObjects, worklists, rules, and roles are all natively covered
  • Beyond K2: AI agents in the workflow, an MCP server, an OAuth 2.0 provider, kanban, documents, retention, and reporting in one platform
  • Fully open-source, free-forever self-hosting for private and on-premises deployment

02

Build workflows and forms programmatically

Everything you design in the visual builder can also be created and managed through the UserTasks API and MCP tools. Generate workflows, forms, pages, data tables, and business rules from code, a CI pipeline, or an AI agent — then version and deploy them across environments. K2 has no equivalent programmatic build surface.

  • REST API and MCP tools author workflows, forms, pages, and decision tables
  • Export/import and GitHub sync give versioned, environment-to-environment deployment
  • Scriptable, AI-assisted application generation — not only point-and-click design

03

Map K2 concepts to UserTasks capabilities

Start with a capability inventory rather than screen-by-screen recreation. K2 workflows map to visual workflows and sub-workflows; SmartForms-style user experiences map to forms and pages; SmartObjects-style abstraction maps to objects, custom tables, and integration references.

  • Activities and events → workflow triggers, logic, actions, and callbacks
  • Worklists and tasks → task inboxes, queues, outcomes, SLAs, and escalation
  • Rules and expressions → page/form rules, workflow logic, and decision tables

04

Discover what the application really depends on

Legacy solutions often contain dependencies that are not obvious from the primary workflow: service instances, environment fields, role resolution, custom controls, SQL procedures, email templates, scheduled jobs, and operational repair procedures.

  • Inventory active applications, owners, volumes, and business criticality
  • Trace integrations, credentials, data contracts, and callback dependencies
  • Measure exceptional paths, manual interventions, and incomplete instances

05

Migrate by process outcome

Choose a representative process and rebuild it as a governed UserTasks application. Validate behavior and evidence before scaling the migration factory across simpler and more critical workloads.

  • Recreate the data and integration contract first
  • Build forms, tasks, rules, and workflow orchestration around that contract
  • Run scenario, permission, load, recovery, and reconciliation tests before cutover

Implementation path

Move from evaluation to a working process

STEP 1

Portfolio assessment

Classify K2 applications by complexity, usage, business impact, integrations, and retirement potential.

STEP 2

Capability mapping

Map workflows, forms, objects, roles, reports, schedules, and custom code to target UserTasks assets.

STEP 3

Pilot migration

Rebuild one representative application and produce reusable patterns, tests, and migration estimates.

STEP 4

Wave-based cutover

Migrate grouped applications with reconciliation, rollback, owner acceptance, and retirement controls.

UserTasks Cloud

Start with a managed, tenant-isolated workspace and move quickly from design to production operation.

Private or on premises

Plan an organization-controlled deployment for private networking, infrastructure ownership, and data-location requirements.

Frequently asked questions

Does UserTasks cover everything K2 does?

Yes. Every core K2 capability — SmartWorkflows, SmartForms, SmartObjects, worklists and tasks, rules, roles, and on-premises deployment — has a first-class equivalent in UserTasks, and the platform adds more on top: AI agents, an MCP server, an OAuth 2.0 provider, kanban, documents, retention, reporting, and programmatic build via API. What no responsible platform promises is a fully automatic, screen-by-screen conversion; applications are rebuilt in a controlled migration using UserTasks capabilities and portability tools.

Can I build workflows and forms programmatically?

Yes. In addition to the visual builders, UserTasks exposes a REST API and MCP tools to author and manage workflows, forms, pages, data tables, and decision tables from code, CI pipelines, or an AI agent, with export/import and GitHub sync for versioned deployment across environments.

What replaces K2 SmartObjects?

UserTasks objects provide a reusable business layer over custom tables and integration references. They expose governed list, get, insert, update, and delete operations to workflows, forms, pages, reports, APIs, and agents.

Can a K2 replacement remain on premises?

Yes. UserTasks has a private and on-premises deployment path for migrations that require private networking, data control, or infrastructure ownership.
