Migrate from Higher Logic Thrive to Mailchimp

Higher Logic Thrive Contact and Member records migrate to Mailchimp Members within a designated Audience. Each record's email address is the dedupe key. First name, last name, phone, address, and all active demographic fields migrate to standard Mailchimp member fields or Merge Fields. We run a pre-migration encoding check and flag any malformed email addresses or records with null email before import so the customer can correct source data rather than receiving rejects post-import.

Higher Logic Thrive Custom Fields (up to 30 per account) used for personalization tokens map to Mailchimp Merge Fields. Standard field types (text, date, number) map directly; checkbox and multi-select fields require decomposition into separate boolean Merge Fields or comma-delimited text fields. Mailchimp caps Merge Fields at 40 per Audience on Standard and Premium tiers, so we audit the full Custom Field inventory during scoping and flag any overflow for the customer to resolve before migration.

Higher Logic Thrive Community Groups map to Mailchimp Segments within the migrated Audience. Each group membership becomes a Segment containing the members assigned to it. We export the group-to-member relationship table during scoping, build the Segment criteria during migration, and validate that member counts match between the Higher Logic Group export and the Mailchimp Segment membership after import.

Higher Logic Thrive Security Groups (access-control groups, not email-send groups) map to Mailchimp Tags rather than Segments. Tags in Mailchimp are informational labels without send criteria, making them a better fit for access-control semantics than Segments, which are defined by filter conditions. We flag this distinction during scoping and confirm the customer prefers Tags over Segments for Security Group translation.

Higher Logic Thrive List Builder segments and Group Manager email lists may need to split across one or more Mailchimp Audiences depending on whether the segments overlap. Non-overlapping segments migrate as Mailchimp Segments within a single Audience. Segments that share no members can be consolidated into one Audience with multiple Segments; segments with overlapping membership require either separate Audiences or Tags for disambiguation. We recommend the split strategy during scoping.

Higher Logic Thrive Campaign bodies and message content migrate as static campaign content to Mailchimp Campaigns. We export HTML body content and preserve inline images as hosted URLs. Subject lines, from names, and send history (send date, open rate, click rate if available) migrate to Mailchimp campaign metadata. Trigger conditions, automation logic, and workflow conditions do not migrate; they require recreation as Mailchimp Customer Journeys post-migration. We deliver a written Customer Journey rebuild guide as part of the handoff.

Higher Logic Thrive Event records (registrations, attendance tracking) have no direct Mailchimp equivalent. We export event records and attendee associations as a structured CSV file for the customer's admin to review and manually reconstruct in Mailchimp if needed. Event migration is out of standard scope but can be included as an add-on if the customer requires API-based attendee import into a specific Mailchimp Audience or tag structure.

Higher Logic Thrive Discussion posts and forum content are not migrated to Mailchimp. Mailchimp is an email marketing platform and does not have a discussion forum or community post object. We export discussion metadata (post count per thread, author, timestamp) as a CSV inventory for the customer's admin to review. If the customer is retaining any community functionality elsewhere, the discussion export can be used to seed content in a different community platform.

Higher Logic Thrive Resource Library entries and attached files are not migrated to Mailchimp. We export the file directory and path references as a CSV so the customer can audit what files existed and re-host them externally. Mailchimp campaign emails reference external URLs for hosted content, but Mailchimp does not store a file library. Any file links in migrated campaign content are re-pointed to the customer's chosen hosting solution during content migration.
