These are the architectural mismatches and technical hurdles specific to a Zammad to Zammad migration.
Zammad provides no built-in Zammad-to-Zammad migration tool, requiring teams to manually select and execute one of four distinct technical paths depending on deployment type and migration goal.
A pg_dump produced on a higher PostgreSQL version cannot be restored to an older cluster, and some restore paths produce a successful exit code even when data is silently missing, requiring mandatory row-count verification after restore.
After any host move or version upgrade, the Elasticsearch or OpenSearch index must be fully rebuilt, which can take hours on large instances and leaves search non-functional until complete.
Without explicitly enabling import mode on the target instance before API-based migration, Zammad fires notifications, triggers automations, and overwrites original timestamps on every imported record.
Attachments stored on the filesystem versus in the database require different handling, and mismatches between source and target storage provider configurations will cause attachment loss during restore.
Merging multiple Zammad instances requires fully custom API-to-API scripting with careful dependency ordering, as there are no official helper scripts for selective ticket or group-level transfers.
Our migration engineer precisely maps every data point from Zammad to Zammad, ensuring perfect continuity for your customer support operations.

“One of the easiest migrations I've ever been through. The team took care of everything — all our data, customer interactions and macros. The process was clear, straightforward and we felt supported all the way. An absolutely seamless experience for our support team and our customers.”
“Fantastic at both guiding us through the process and helping us fix things as they come up and dial them in.”
“The ease of the process and that ClonePartner was informing me what was going on at every step. If you're on the fence, do it. ClonePartner are great!”
“They were SO helpful. We had a few hiccups because our migration was in the middle of the process, but they were really flexible and did multiple delta migrations for us. We were able to map a lot of our old ticket data so it's usable for comparisons in the future.”
“Overall a great experience. We had to go back a few times to get everything just right, which was totally expected. The transition was smooth, and there was no data loss.”

Use backup/restore for full Zammad clones. For selective moves or instance merges, use API scripting with import mode, external ID mapping, and delta sync.

How to Export Data from Zammad: Methods, API Limits & Portability
Zammad has no bulk export UI. Use the REST API with expand=true and pagination, PostgreSQL dumps for self-hosted instances, or the Rails console for targeted exports.
Choosing the right approach is key because migrating from Zammad to Zammad isn't just about moving data – it's about protecting customer relationships.
