+# Migration steps: from Knapsack to Knapsack Pro
+
+Follow these steps to migrate from `knapsack` to `knapsack_pro` in 10 minutes.
+
+Commands are provided to help you with each step.
+
+On Linux, you need to remove the `''` part from the `sed` commands. Also, you can ignore the `sed: no input files` warning that is printed when there's no substitution to perform.
+
+## Steps
+
+- [ ] Remove the `knapsack` gem:
+   ```bash
+   bundle remove knapsack
+   ```
+
+- [ ] Remove `Knapsack.load_tasks` from the `Rakefile` if present:
+   ```bash
+   sed -i '' '/Knapsack\.load_tasks/d' Rakefile
+   ```
+
+- [ ] Replace `require "knapsack"` with `require "knapsack_pro"`:
+   ```bash
+   grep --files-with-matches --recursive "require.*knapsack" . | xargs sed -i '' "s/'knapsack'/'knapsack_pro'/g"
+   grep --files-with-matches --recursive "require.*knapsack" . | xargs sed -i '' 's/"knapsack"/"knapsack_pro"/g'
+   ```
+
+- [ ] Remove the following code from the test runner configuration:
+   ```diff
+   - Knapsack.tracker.config({
+   -  enable_time_offset_warning: true,
+   -  time_offset_in_seconds: 30
+   - })
+
+   - Knapsack.report.config({
+   -  test_file_pattern: 'spec/**{,/*/**}/*_spec.rb', # ⬅️ Take note of this one for later
+   -  report_path: 'knapsack_custom_report.json'
+   - })
+   ```
+
+- [ ] Replace `Knapsack` with `KnapsackPro`:
+   ```bash
+   grep --files-with-matches --recursive "Knapsack\." . | xargs sed -i '' 's/Knapsack\./KnapsackPro./g'
+   grep --files-with-matches --recursive "Knapsack::" . | xargs sed -i '' 's/Knapsack::/KnapsackPro::/g'
+   ```
+
+- [ ] Rename `KnapsackPro::Adapters::RspecAdapter` to `KnapsackPro::Adapters::RSpecAdapter`:
+   ```bash
+   grep --files-with-matches --recursive "KnapsackPro::Adapters::RspecAdapter" . | xargs sed -i '' 's/RspecAdapter/RSpecAdapter/g'
+   ```
+
+- [ ] Remove any line that mentions `KNAPSACK_GENERATE_REPORT` or `KNAPSACK_REPORT_PATH`:
+   ```bash
+   grep --files-with-matches --recursive "KNAPSACK_GENERATE_REPORT" . | xargs sed -i '' '/KNAPSACK_GENERATE_REPORT/d'
+   grep --files-with-matches --recursive "KNAPSACK_REPORT_PATH" . | xargs sed -i '' '/KNAPSACK_REPORT_PATH/d'
+   ```
+
+- [ ] Rename ENVs from `KNAPSACK_X` to `KNAPSACK_PRO_X`:
+   ```bash
+   grep --files-with-matches --recursive "KNAPSACK_" . | xargs sed -i '' 's/KNAPSACK_/KNAPSACK_PRO_/g'
+   ```
+
+- [ ] Remove all the reports:
+   ```bash
+   rm knapsack_*_report.json
+   ```
+
+- [ ] [Configure Knapsack Pro](https://docs.knapsackpro.com/knapsack_pro-ruby/guide/)
+
+- [ ] Ensure all the CI commands are updated:
+   ```bash
+   grep --files-with-matches --recursive "knapsack:spinach" . | xargs sed -i '' 's/knapsack:spinach/knapsack_pro:spinach/g'
+   grep --files-with-matches --recursive "knapsack:" . | xargs sed -i '' 's/knapsack:/knapsack_pro:queue:/g'
+   grep --files-with-matches --recursive "CI_NODE_TOTAL" . | xargs sed -i '' 's/CI_NODE_TOTAL/KNAPSACK_PRO_CI_NODE_TOTAL/g'
+   grep --files-with-matches --recursive "CI_NODE_INDEX" . | xargs sed -i '' 's/CI_NODE_INDEX/KNAPSACK_PRO_CI_NODE_INDEX/g'
+   ```
+
+- [ ] If you removed `test_file_pattern` when deleting `Knapsack.report.config`, use [`KNAPSACK_PRO_TEST_FILE_PATTERN`](https://docs.knapsackpro.com/ruby/reference/#knapsack_pro_test_file_pattern) instead

-Do you know Knapsack Pro Ruby gem is available as Heroku add-on? It works with your current CI server.
-https://elements.heroku.com/addons/knapsack-pro
+<br />
+<br />
 
-Knapsack Pro has Queue Mode that will split Ruby & JS tests in a dynamic way across parallel CI nodes to ensure each parallel job takes a similar time. Thanks to that there is no bottleneck in your CI pipelines.
+Knapsack wraps your current test runner and works with your existing CI infrastructure to split tests optimally.
 
-__See introduction how the Knapsack Pro add-on works__
-https://youtu.be/rmXES2N0_QU
+It comes in two flavors, `knapsack` and `knapsack_pro`:

-* Knapsack Pro is risk-free integration! Knapsack Pro runs tests in Fallback Mode if your CI servers can't reach our API for any reason.
-* We don't need access to your repository. Knapsack Pro is just wrapper around test runner like RSpec, Cucumber, Minitest etc.
-* Hundreds of developers use Knapsack Pro every day to run fast CI builds.
-* It works with other programming languages.
