NS90: Migrate:

Sage MAS 90 to NetSuite

Still on Sage MAS 90? Move a decade of history to NetSuite.

NS90: Migrate works with older MAS 90 data even when it can't be queried, maps it with our Sage 100 logic, and rebuilds items, bills of materials, quotes, rentals and ten years of balances in NetSuite.

WHY NOW

10+ years

MAS 90 version 4.4 has been out of support since September 30, 2014

MAS 90 became Sage 100 in 2012, and current Sage 100 support covers only the latest release and the two before it. A MAS 90 system has no updates, no vendor support and often no one left who knows its files. NS90 gets the data out while it's still readable.

What we’ve learned on Sage MAS 90 projects

The Sage MAS 90 details that make or break a migration

These come from real NS90 Sage MAS 90 projects. Each is already built into our standard Sage MAS 90 mapping, so you don’t discover it at UAT.

Test ODBC on day one

MAS 90 drivers can list tables but fail to read them. We test real reads in week one and switch to structured exports straight away if they fail.

Exports in our template, not ad-hoc

When data comes out as CSV, it comes out in the NS90 template layout, so it lands and maps exactly like a database extract.

Periods recovered from file names

Older exports can arrive without headers or posting periods. We derive the period from the file and validate every month against the trial balance.

Matrix items need a list

MAS 90 has no flag for matrix or variant items. We get the list from you early and load matrix items as their own NetSuite records.

Ad-hoc lines and misc codes

Non-stock lines and special charge codes become NetSuite other-charge or non-inventory items, with the original description kept on the line.

BOMs by location

Location-specific bills of materials load as uniquely named NetSuite BOMs assigned to each location.

Tax codes, harmonized

MAS 90 tax schedules are mapped to NetSuite tax codes at line level and tested on open quotes and orders.

Every refresh planned

Each MAS 90 refresh takes several hours of extraction plus load time, so refreshes are scheduled into the plan from the start.

Future-dated balances spotted

Trial balance files that run into future periods, such as scheduled depreciation, are flagged and cut at go-live.

Integrity checks before export

ProvideX files are checked with Sage's data utilities before export.

Legacy and newer modules side by side

Older MAS 90 modules use different file layouts; we map each one separately.

How NS90: Migrate works

From Sage MAS 90 to a reconciled NetSuite in six steps

Every step runs on NS90 Migrate, MHI’s cloud-native migration engine on NSIP and NSAW. It handles extraction, landing, harmonization, parallel loading and trial-balance validation as repeatable jobs, so each rehearsal and the final delta pull run the same way.
