IFS upgrade cost and timeline: what drives the number
The cost and timeline of an IFS upgrade or IFS Cloud migration depend mainly on your customisation footprint, the number of modules and sites, data complexity, and your integration estate — there is no fixed price, and an estate assessment is the only reliable way to scope it.
- Customisation footprint is the single biggest cost driver.
- There is no one-size-fits-all price — scope it with an estate assessment.
- Cutting customisation and cleaning data up front reduces both cost and risk.
What drives the cost
A handful of factors explain most of the variation between a quick upgrade and a major programme.
- Customisation footprint — how far you have drifted from standard IFS
- Number of modules, entities and sites in scope
- Data volume, quality and migration complexity
- The integration and reporting estate that must be rebuilt
- Whether you re-implement or technically migrate
Typical timeline shape
A near-standard technical migration can be measured in months; a full re-implementation of a heavily customised, multi-site estate takes considerably longer. Rather than quote a generic range, we scope a realistic timeline during the estate assessment — anything else is guesswork.
How to reduce cost and risk
You have more control over the number than you might think.
- Retire customisations you no longer need
- Improve data quality before migrating, not during
- Adopt new standard IFS Cloud capability instead of rebuilding old custom code
- Sequence the programme so value lands early
Frequently asked questions
How much does an IFS upgrade cost?
There is no fixed price — it depends on customisation, modules, sites, data and integrations. An estate assessment produces a realistic, defensible scope and budget.
How can we make an IFS upgrade cheaper?
Retire unnecessary customisations, clean data early, adopt standard capability over custom rebuilds, and sequence the work so value lands early.
