I have an ArcGIS Enterprise deployment consisting of two machines that I recently migrated from one Microsoft Azure tenant to another (same region). Following the migration, approximately 20% of the map services are failing to start in the new tenant environment.
Environment Details
Two-machine ArcGIS Enterprise deployment
No high availability configured
Same Azure VM sizes in both tenants
Migration performed using the WebGISDR tool
WebGISDR restore completed successfully (100% success reported)
- Same Public URL (Webcontext URL being used)
Issue Description
A subset of map services with referenced SDE data sources (Azure SQL) are failing.
Hosted services are functioning normally.
Some map services using the same SDE data source are working correctly, while others are not. This suggests the issue may not be related to database connectivity or firewall configuration.
Errors Observed
When accessing the affected services through REST:
Occasionally:
Additional Notes
The affected services are configured to use shared instances, and I am unable to change them to dedicated instances.
I am unable to stop or delete the impacted services from either Portal (delete item) or ArcGIS Server Manager.
I cannot overwrite the failing services.
However, I am able to successfully publish a new service (with a different name) using the same APRX and data source.
Given that:
WebGISDR restore reported full success,
VM sizes and region are unchanged,
Some services using the same data source work correctly,
I would appreciate guidance on what could cause partial service initialization failure after tenant migration, particularly for referenced SDE services running in shared instance mode.
