iShield Resource Library, Plan & Design · Migration scenarios
Three starting points. One honest path.
No rip-and-replace fantasy. Pick the estate that looks most like yours — see exactly which systems get connected, augmented, or replaced, in what order, and through which integration.
What they're dealing with
- SAP is the truth — nothing can break it
- Service desk is email + spreadsheets
- Sales lives in Excel, no pipeline visibility
- Integrations are point-to-point and brittle

Phase 1 — Connect
Weeks, not months. Zero replacement.
iShield Link sits in front of SAP as a governed API layer. SAP stays as the system of record; everything else gets a clean way to read and write to it.

Operating principles
The rules behind every adoption path
Connect before you change
Link broker first. Existing systems stay untouched. You get optionality without disruption.
Augment where it pays
Add iShield products only where they fill a real gap or replace fragile tooling. No big-bang.
Replace only when it earns it
Migration is selective and reversible. Link keeps the cut-over safe and the rollback possible.
