Abstract
A migration manager (MM) identifies a source group of compute instances (at a first partition of a provider network) to be migrated to an isolated virtual network (IVN) implemented in a second partition. The MM triggers the establishment within the IVN of an equivalence group of instances corresponding to the source group instances. Connectivity between the equivalence group and a first load balancer which was being used for the source group in the first partition is maintained by modifying one or more configuration settings. After a replacement load balancer is established within the IVN, the first load balancer is decommissioned.

-20. (canceled)
A method, comprising:
- performing, at one or more computing devices:
- determining that a set of compute instances of a first logical partition of a virtual computing service is to be migrated to a second logical partition;
- causing connectivity to be established between (a) a first load balancer configured for a first subset of the set of compute instances and (b) one or more replacement compute instances, established in the second logical partition, corresponding to the first subset;
- and
- initiating establishment, within the second logical partition, of a replacement load balancer for the first load balancer.
A system, comprising:
- one or more computing devices;
- wherein the one or more computing devices include instructions that upon execution on or across one or more processors cause the one or more computing devices to:
- determine that a set of compute instances of a first logical partition of a virtual computing service is to be migrated to a second logical partition;
- cause connectivity to be established between (a) a first load balancer configured for a first subset of the set of compute instances and (b) one or more replacement compute instances, established in the second logical partition, corresponding to the first subset;
- and
- initiate establishment, within the second logical partition, of a replacement load balancer for the first load balancer.
One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors cause one or more computer systems to:
- determine that a set of compute instances of a first logical partition of a virtual computing service is to be migrated to a second logical partition;
- cause connectivity to be established between (a) a first load balancer configured for a first subset of the set of compute instances and (b) one or more replacement compute instances, established in the second logical partition, corresponding to the first subset;
- and
- initiate establishment, within the second logical partition, of a replacement load balancer for the first load balancer.
