Short answer: Not retroactively — but here's what you can do for each group.
Suggestions — Prospects that haven't been actioned yet will automatically be enrolled in the currently active sequence; no action is needed.
Pending (connection request sent, not yet accepted) — These prospects are already mid-flow. Once they accept, they'll continue following the original sequence. You can't retroactively change the sequence for them.
Connected / Replied — You can manually move these prospects to a new campaign.
See our guide on moving prospects between campaigns.
Best practice: Always finalize your sequence before activating a campaign. If you need to update messaging, create a duplicate campaign with the new sequence and route new prospects there.
