Why imports from MS Project are important

Many companies use Microsoft Project as their planning tool but later require a consolidated project landscape in Oracle Primavera P6. However, importing files from MS Project into P6 involves considerable risks when performed without a supporting tool. This is because the data must be saved in MS Project as an XML file in order to be imported into P6. During this process, inaccuracies in conversion, incomplete structures or incorrect data may occur, which can quickly burden the P6 database and significantly impair the quality of the schedules.

The proimporter was developed precisely for this scenario. The tool enables fast, precise and secure imports of MPP files into a Primavera P6 target database, allowing data to be exported from MS Project as an MPP file. This not only improves data quality but also makes the entire import process significantly more stable.

Challenges with MS Project imports into P6

Typical issues arise when importing MS Project data into Primavera P6 using the native XML process:

• Structures from Microsoft Project are not always transferred 1:1 into P6.
• Resources, calendars and codes may be unintentionally duplicated.
• The import process offers very limited options for control or pre‑validation.
• When using the P6 standard import, “data clutter” frequently enters the P6 database and can only be cleaned up later with considerable effort.

These risks are particularly critical for companies that need to migrate many schedules from MS Project and want to avoid contaminating their P6 database and global data.

Import of MPP-files into Primavera P6: The biggest advantage of the proimporter

A key USP of the proimporter is the ability to import MPP files into the Primavera P6 target database. Without the proimporter, this process is only possible via XML files generated in MS Project.

At the same time, users can selectively decide which content from the MS Project file should actually be transferred. Instead of an “all‑or‑nothing” import, only the elements that are truly relevant for the P6 project are imported. This keeps the database clean and consistent.

Controlled imports instead of taking over data on a wing and a prayer

The proimporter places the focus on transparency and control:

Before an MS Project schedule is finally written into P6, the tool analyzes the file and clearly displays potential conflicts. Users can see at an early stage which data will be imported and where possible inconsistencies exist. Errors can therefore be corrected before they enter the database.

This step is essential because unvalidated imports often lead to duplicate resources, calendars or project structures that later require extensive cleanup. The proimporter helps prevent such avoidable database issues from arising in the first place.

Working more efficiently: Less effort & higher quality

The import of MS Project data into Primavera P6 is often part of a regular project process. When this step is carried out without the proimporter , it repeatedly creates risks, follow‑up questions and a high level of administrative effort. The proimporter significantly streamlines the process:

• Guided import steps instead of unstructured click sequences
• Clear conflict notifications before the import
• Automated checks instead of manual analyses
• A consistent workflow for all users

For organizations working with a high number of MS Project schedules, this results in a substantial reduction of rework and consistently high data quality.

proadvise expertise: Professional tool and in-depth help combined

Behind the proimporter stands proadvise GmbH, a specialized provider of PM and IT services centered around Oracle Primavera P6.

For customers, this means the following:

They do not only receive a powerful import tool, but also gain access to experienced Primavera experts who can support the setup of import processes, the design of data structures and questions related to the P6 system landscape. This combination of software and consulting is especially valuable for companies that want to strategically develop their P6 environment and maintain long‑term stability.

Conclusion: The proimporter has many advantages over classic MS project imports

The comparison makes it clear.

Importing XML files from MS Project into Primavera P6 involves significant risks and often results in time‑consuming rework. In contrast, the proimporter enables a fast, precise and secure import process through the use of MPP files, minimizes errors, prevents unnecessary data clutter and ensures clean, consistent structures within the P6 database.

Overall, the proimporter is the most professional, efficient and reliable solution for integrating data from Microsoft Project into Primavera P6.
