Azure application insights workspace based migration related questions
Hello, We have migrated our classic application insights instances to workspace based successfully. After migration, I see that new data post migration is getting stored in linked log analytics ...
I tried to summarize the case below:
- During the migration process, new telemetry may continue to appear in the classic Application Insights resource for up to 24 hours.
- After the migration cutover is complete, all subsequent telemetry is ingested exclusively into the linked Log Analytics workspace.
- Historical data remains accessible in the classic Application Insights resource until it reaches the end of its configured retention period.
- To analyze both pre‑migration and post‑migration data, queries must be executed against each source separately and the results combined.
