At a Glance

Slack
4.5/5 · 33,000 G2 reviews
  • De facto standard for workplace communication — most PMs will use Slack daily, and it appears constantly in job descriptions
  • 2,600+ app integrations make it the central nervous system of the product team's tool stack, pulling notifications from Jira, GitHub, Figma, and more into one place
  • Channels, threads, and Slack Connect enable structured communication across teams, departments, and even external partners/vendors
Optimizely
4.2/5 · 700 G2 reviews
  • Industry-leading experimentation platform with both client-side and server-side testing — supports the full experimentation lifecycle from hypothesis to results
  • Powerful Stats Engine uses sequential testing methodology that allows peeking at results without inflating false positive rates — a significant advantage over traditional frequentist approaches
  • Robust feature flagging and progressive rollout capabilities allow engineering teams to decouple deployment from release, with fine-grained audience targeting

Migration Steps

1

Audit and export your current workspace

Before touching Optimizely, document what lives in Slack: projects and tasks, custom fields, automations, integrations, and team permissions. Export a full CSV backup — most tools support this from Settings → Export. Pay particular attention to any workflow automations that your team relies on daily.

2

Set up your Optimizely workspace

Create your Optimizely workspace and replicate your project structure using tasks and projects. Run with a single pilot team before migrating everyone.

3

Map your workflow equivalents

Find the closest Optimizely equivalent for each Slack feature your team relies on. projects and tasks in Slack maps to tasks and projects in Optimizely. Optimizely supports custom fields — recreate your Slack field schema here first. Prioritise the critical path: task creation, status tracking, and assignment.

4

Import your data

Optimizely supports CSV import for tasks and projects and has 20+ native integrations. After importing, rebuild your key automations — Optimizely's automation engine can replicate most rules you had in Slack. Start with your most active project rather than importing everything at once.

5

Onboard your team

Run a 30-minute walkthrough covering the daily workflow: how to create tasks and projects, update status, and find your board. Expect a moderate ramp — most engineers and PMs hit their stride within a week. The biggest adjustment is usually the project hierarchy.

6

Run Slack in parallel for two weeks

Keep Slack read-only while your team works primarily in Optimizely. This reduces risk and lets people reference historical context — old decisions, archived tickets, past sprint data — without slowing the migration. After two weeks with no new work going into Slack, archive the workspace and make Optimizely the official home.
