How to update Baseline in Primavera P6

In project management, a baseline is typically fixed and used to measure performance against the original plan. However, in certain cases—such as significant delays or scope changes—it may be necessary to update the baseline. This guide walks you through two methods to update a baseline in Primavera P6.

We have a simple project with an assigned baseline.
After several update periods, the project has deviated significantly from the baseline.
Following discussions with the Owner, approval is granted to update the baseline to match the current schedule.

Method 1: Create a New Baseline from the Current Schedule

Step 1: Configure Earned Value Settings

• Go to Admin > Admin Preferences
• In the Earned Value tab, select:
  “At completion values with current dates”

Step 2: Create a New Baseline

• Go to Project > Maintain Baselines
• Click Add to create a new baseline from the current project

Step 3: Assign the New Baseline

• Go to Project > Assign Baselines
• Select the newly created baseline (e.g., Baseline B2)

Result

Your project now uses the updated baseline aligned with the current schedule.

Method 2: Restore and Update the Original Baseline

Step 1: Assign the Baseline as a Current Project

• Go to Project > Assign Baselines
• Select the baseline and set it as the Current Project

Step 2: Restore the Baseline

• Go to Project > Maintain Baselines
• Select the baseline and click Restore

Step 3: Update the Restored Project

• The baseline is now a regular project
• Open it and make the necessary updates

Step 4: Convert Back to a Baseline

• Open your main project
• Go to Project > Maintain Baselines
• Click Add, then choose:
  “Convert another project to a baseline”
• Select the updated project

Result

Your project now has a new baseline reflecting the updated schedule.
