public Task MigrateAsync(IAddressable grain, SiloAddress? targetSilo = null)

Migrates the current activation of the specified grain to a different silo and waits for migration to complete. If targetSilo is specified, a placement hint is set to guide migration to that silo.

Parameters

grainIAddressable

The grain to migrate.

targetSiloSiloAddress?

The target silo address, or null to let the placement director choose.

Returns

A task that completes when the grain has been migrated (deactivated on the source silo).

Examples

            var targetSilo = cluster.GetActiveSilos().First(s => s.SiloAddress != originalHost).SiloAddress;
            await cluster.MigrateAsync(grain.GetGrainId(), targetSilo);
