ERP Migration Services

SAP’s December 31, 2027 mainstream maintenance deadline for ECC 6.0 (EHP 6–8) is confirmed, with no further extensions planned. A typical S/4HANA migration, as part of the entire ERP implementation project, takes 12 to 24 months depending on customization and data volume. Starting the assessment now gives your team time to prepare data properly instead of compressing the project into a deadline sprint.

Historical data moves according to a retention plan set during the planning phase. The process starts with data extraction covering open invoices, vendor and customer records, and chart of accounts information, accounting for different data formats along the way. How far back transaction-level detail goes depends on how the data is structured today and how much of it remains relevant data the business still needs.

Some disruption is normal during cutover, which is why go-live gets scheduled around low-activity periods where possible, with a parallel-run or rollback option built in for higher-risk environments. Departments such as inventory management are usually the least affected as the data is transferred in controlled batches and data security checks are performed at every stage.

In the legacy system analysis phase, we map them all. Then, we extract data from the old system and rebuild or reconfigure integrations in the new environment. This groundwork is what makes a successful ERP data migration possible instead of leaving the team to rebuild everything after go-live.

Not immediately, but the window to plan properly is shrinking. Microsoft’s mainstream support for Dynamics GP ends December 31, 2029, and migrations of this scale typically take 6 to 18 months, including data cleansing to remove redundant data before anything moves. Starting 12 to 18 months ahead of that date is what turns a rushed project into a successful data migration.
