Hypercare after Dynamics 365 go-live

Hypercare is the elevated-support period that follows a Dynamics 365 go-live. It bridges the project team's deep knowledge of the new system and the steady-state support organisation's growing understanding. Most issues that ever surface, surface here; most habits that ever form, form here.

Duration

Typically two to four weeks for SMB Business Central go-lives; four to twelve weeks for enterprise Finance/SCM. Defined up front in the contract and the project plan — open-ended hypercare wastes money and gives users a false safety net.

Staffing

Hypercare is heavier than steady-state support. Common staffing:

• Floor walkers — partner consultants and customer champions physically (or virtually) present in business teams during their working hours.
• Daily stand-up — partner project team, customer key users, IT support, leadership representative. Surface issues, agree priorities, sign off resolutions.
• War room or fast-track channel — a dedicated Teams channel where users can raise issues that get same-day visibility. Distinct from steady-state ticketing.
• On-call developer/configuration capacity — to address true defects same-day.

What hypercare covers.

• Operational support: how-to questions, password resets, missing permissions, "I can't find the button".
• Configuration tweaks: defaults that were wrong, missing posting groups, unexpected behaviour from a customisation.
• Defect resolution: real bugs that escaped UAT.
• Performance issues: things that ran fine at sandbox volume but stutter at production volume.
• Training reinforcement: the user who didn't attend training, the user who attended but didn't absorb.

Severity discipline

Triage every issue:

• Severity 1 — work-stopping. Fix in hours.
• Severity 2 — workaround acceptable for a day. Fix in days.
• Severity 3 — annoying. Fix in weeks.
• Severity 4 — enhancement request. Fix in post-go-live optimization phase or later.

The hardest discipline is not fixing Sev 3/4 things in hypercare. Resist scope creep; rest is finite.

Knowledge transfer

During hypercare, the steady-state support team learns the system. By end of hypercare, support escalations to the partner should be the exception, not the rule. Document fixes as they happen — runbooks for the recurring issues — so the next hypercare period is shorter.

Exit criteria

Before declaring hypercare over:

• No open Sev 1 issues.
• Open Sev 2 backlog under an agreed cap.
• Customer support team handling 80%+ of incoming volume.
• Leadership sign-off.

Don't skip celebration

A go-live successfully through hypercare is a real accomplishment for the team. Mark it.

Where to go next

Hypercare hands over to run-book operations, with monitoring and observability as the early-warning system and release management as the rhythm that replaces it. What went into the window is cutover planning; what keeps tickets down is training strategies.
