Considerations for modifying a replication link

These considerations apply to modifying replication links:

You can modify a replication link in the HCP System Management Console for either system involved in the link.

You can modify a replication link at any time.

You can change an active/passive link to an active/active link, but you cannot change an active/active link to an active/passive link.

When changing an active/passive link to active/active, you need to ensure that replication checkpoints are up to date before converting, otherwise you risk losing directory metadata.

You cannot change the direction of an active/passive link.

If you change the domain name or IP addresses for either system involved in a link, the new domain name or IP addresses must identify the same system. The exception to this is when you’re reconfiguring the link before restoring it to a new or rebuilt system.

When you change an active/passive link to an active/active link, HCP suspends activity on the link. You need to resume activity on the link manually. For information about resuming activity on link, see Suspending and resuming activity on an individual link.

While updating link properties other than the link type, HCP temporarily suspends activity on the link.
