The Challenge: Reducing Slack Costs Without Losing Organizational Knowledge
For large organizations, Slack Enterprise Grid provides capabilities designed for managing collaboration across multiple workspaces. However, as business priorities change, organizations may reassess their licensing requirements and look for opportunities to optimize costs.
In this engagement, the client decided to move from Slack Enterprise Grid to Slack Business+ as part of a cost-cutting initiative.
The challenge was that the organization had accumulated a substantial amount of collaboration data and operational complexity. Thousands of channels, hundreds of thousands of files, individual and group direct messages, workflows, custom applications, and other Slack resources needed to be accounted for in the transition.
This was not a simple workspace migration. Moving from Enterprise Grid to Business+ required careful planning around the destination organization, user setup, data migration, application dependencies, and the differences between the two plans.
The objective was clear: complete the transition to Business+ while migrating the agreed collaboration data and minimizing disruption to employees.
The Solution: A Comprehensive Slack Enterprise Grid to Business+ Migration
Implementology delivered migration and implementation work, covering data migration, destination setup, integrations, Slack Connect support, and user enablement in 4 weeks.
1. Migration Planning and Destination Setup
We planned the transition around the client's target Business+ environment and the scope of its existing Slack data.
Our work included:
Preparing the destination Business+ organization and workspace environment.
Setting up users for the destination environment.
Planning the migration of existing collaboration data and resources.
Coordinating migration dependencies and destination configuration.
Supporting the transition from the Enterprise Grid environment to Business+.
The client managed its own single sign-on (SSO) and SCIM configuration. Implementology focused on the migration and workspace setup activities within our agreed scope.
2. Large-Scale Channel and Message Migration
Preserving collaboration history was central to the engagement. Employees needed access to the information and conversations relevant to their ongoing work.
Implementology migrated an extensive volume of channel and messaging data, including:
3,600+ public channels
2,900+ private channels
Individual direct messages
Group direct messages
Migrating both public and private channels required attention to channel membership, access boundaries, and the resources associated with each channel.
Direct messages and group direct messages were also included in the migration scope, helping preserve important one-to-one and group conversations rather than limiting the transition to channel history.
3. Migrating More Than 600,000 Files
Files shared in Slack often become part of an organization's working knowledge, including project documents, operational references, and historical attachments.
As part of this engagement, we migrated more than 600,000 files.
This volume added another layer of complexity to the migration, requiring the team to account for the scale of the organization's shared content alongside its messages and channel structures.
4. Canvas, Lists, and Custom Emojis
A Slack environment contains more than channels and messages. Teams also rely on collaborative documents, lightweight tracking tools, and custom visual elements.
The migration included:
250 Canvases
13 Lists
5,700+ custom emojis
T
hese resources were included alongside the core channel and messaging migration to address the broader collaboration experience.
Custom emojis, in particular, can be deeply embedded in an organization's communication culture. Migrating them helped retain familiar elements of everyday Slack conversations.
5. Workflow Migration and Custom App Support
Large Slack environments often depend on automation and custom integrations to support business operations.
The client had a substantial collection of workflows and custom applications that needed to be addressed as part of the transition.
Implementology migrated:
218 workflows
89 custom apps
These components required consideration beyond the transfer of channel data. Workflows and applications can depend on workspace-specific resources, permissions, credentials, and integrations.
Our migration scope accounted for these operational components as part of the wider transition to Business+.
6. Slack Connect Support
Slack Connect enables organizations to collaborate with external partners, customers, and other businesses directly within Slack.
A workspace migration can affect these external collaboration relationships, so they need to be considered separately from internal channel migration.
Implementology provided Slack Connect support as part of the engagement, helping coordinate the work required to address external collaboration during the transition.
This ensured that Slack Connect was treated as an important workstream rather than an afterthought.
7. Channel Archiving and Channel Manager Reassignment
Workspace transitions also create an opportunity to review channel administration and ensure that ownership is appropriately configured in the destination environment.
As part of the migration, Implementology addressed the re-archiving of previously archived channels and the reassignment of channel managers.
These activities helped align channel administration with the new environment and the organization's ongoing operational requirements.
8. User Support, Office Hours, and Change Enablement
A technically successful migration is only part of the job. Employees also need to understand what has changed, how to access resources, and where to get help.
To support the transition, Implementology provided a combination of:
Live support within the Slack workspace to help users navigate issues as they arose.
Office hours where users could ask questions and get assistance.
Video explanations to communicate migration-related changes and help users understand the new environment.
Practical guidance for users adapting to the destination workspace.
This approach gave employees multiple ways to get help throughout the transition, rather than leaving them to work through changes on their own.
The Results: A Large-Scale Migration Delivered Across 4 weeks
The engagement covered a substantial volume of collaboration data and operational resources as the organization moved from Enterprise Grid to Business+.
