Version mismatch prevents import of realm data from zulipcloud to self-hosted intance #32826
Closed
Description
Description:
Trying to import a data export from zulipcloud on version 10.0-dev-2143-gd3df54f54c into self-hosted installation which is on zulip-cloud-current branch using manage.py import function.
What is not as expected:
The import script stops with an error due to a version mismatch between the exported data and the self-hosted zulip server.
Steps to reproduce:
- New self-hosted installation on Debian 12
- Upgrade self-hosted installation to zulip-cloud-current
/home/zulip/deployments/current/scripts/upgrade-zulip-from-git zulip-cloud-current - Self-hosted version results in 10.0-dev-2114-g06d04b4291
- Exported data from Zulipcloud version 10.0-dev-2143-gd3df54f54c
- Exporting data on zulipcloud
- Trying to import on self-hosted installation by
sudo su zulip -c '/home/zulip/deployments/current/manage.py import "testimport" /home/zulip/zulip-export-zlj7_d82'
Results in error:
sudo su zulip -c '/home/zulip/deployments/current/manage.py import "testimport" /home/zulip/zulip-export-zlj7_d82'

I also tried to update the self-hosted version to main (10.0-dev-2278-g3eb501fa18), which results in the same/expected error message:
