Most large organisations run more monitoring tools than they can name. Consolidating onto one platform is the right instinct. Most consolidations fail anyway, and they fail in the migration, not the selection.
What goes wrong
The new platform is chosen, the old tools are given a decommission date, and in between there is a period where the old tools are half switched off and the new one is half configured. Alerts go missing. A team that trusted its old dashboard loses it and quietly keeps a copy running. Two years later there are five tools instead of four.
How C4C approaches it · all three Cs
Consolidation is planned as a sequence of coverage handovers, service by service, with the old and new tools running side by side for each one until the receiving team confirms it can see what it used to see and more. Context is rebuilt deliberately, because the topology and business meaning in the old tools rarely migrates on its own. Cause is the acceptance test: the new platform has to find the root cause of a known past incident faster than the old estate did before that estate is switched off.
What you instrument and how deep. Full depth, infrastructure only, or discovered but not monitored, decided on purpose for every part of the estate.
The topology and the business meaning attached to the telemetry, so a technical signal arrives already attached to its consequence.
Getting from symptom to root cause in minutes rather than hours. One problem, one cause, the owner obvious. It only works when Coverage and Context are right.

Questions
Because the migration is treated as a switch rather than a sequence. Teams lose visibility they relied on, keep the old tool running unofficially, and the estate ends up with more tools than before. Consolidation succeeds when each service is handed over deliberately and the old tool is only switched off once the new one has proven itself.
It depends on the number of services and teams, not the number of tools. A plan sequenced by service, with side by side running for each, is slower to start and much faster to finish than a big bang cut over.
Take a real past incident and check that the new platform finds its root cause faster than the old estate did. If it cannot, the migration is not finished, regardless of what the project plan says.
