Maritime CMMS data migration is the process of transferring vessel maintenance data — equipment registers, planned maintenance schedules, spare parts catalogues, maintenance history, and procurement data — from one Computerised Maintenance Management System to another. It is one of the most complex and operationally consequential data management activities a shipping company undertakes.
Maritime operators migrate CMMS platforms for a range of reasons: a group decision to standardise on a single CMMS across the fleet; an acquisition that brings vessels onto a different system; the end of a legacy system’s commercial support; or a strategic move to a more capable platform that better supports fleet management, procurement, and reporting. The most common migrations involve transitions between AMOS, ShipNet, STAR Suite, and NavFleet, or migrations from these platforms to newer cloud-based systems.
The outcome of a maritime CMMS migration depends almost entirely on the quality of the data that is migrated. If the source system contains incomplete, incorrect, or poorly structured data, migrating that data into the new system does not improve it — it replicates the same problems in a new environment, at the cost and disruption of a migration project.

The most common cause of maritime CMMS migration failure — delayed go-live, poor data quality in the target system, and continued reliance on the legacy system after the planned migration date — is attempting to migrate source data that has not been assessed, cleansed, and structured before migration begins.
The most frequent source data quality problems that cause migrations to fail include:
In Sharecat Data Services’ experience, the cost of remediating data quality problems after a maritime CMMS migration is consistently higher — often by a factor of three or more — than the cost of addressing those problems before migration.
A successful maritime CMMS migration requires treating data quality as a precondition of the migration, not an afterthought. Sharecat Data Services works with maritime operators to prepare their vessel data for migration — assessing the current state of CMMS data, cleansing and enriching it to meet the requirements of the target system, and structuring it for clean, complete loading into the new platform.
Sharecat Data Services' migration support covers: full source data profiling to identify completeness gaps and structural mismatches with the target system; data cleansing and data enrichment against a proprietary reference database of approximately one million verified OEM records; field-level data mapping and transformation between source and target system structures; migration validation confirming completeness and accuracy before go-live; and post-migration data quality verification confirming the target system correctly supports maintenance scheduling, procurement, and reporting from day one.
Sharecat Data Services has direct experience of the data structures, field requirements, and import formats of AMOS, ShipNet, STAR Suite, NavFleet, and other maritime CMMS systems. This means migration projects move faster and with less risk than when data preparation is attempted without maritime CMMS expertise. Every project includes a before-and-after statistical comparison so the improvement is measurable.
Our maritime CMMS data migration expertise builds on Sharecat Data Services' broader CMMS and ERP data migration services, applied across heavy and complex industries including energy, chemicals, and renewables.
