Post "comment_id" lost when migrating content to new instance

[triestpa]

Issue Summary

As a workaround for a breaking issue with the Ghost-CLI (TryGhost/Ghost-CLI#461), I recently attempted to migrate my blog to a new server.

Importing the JSON content from the old instance to the new one resulted in the comment_id property for each post changing. The themes on both instances are identical; both are initializing the Disqus config with -

this.page.identifier = 'ghost-{{comment_id}}';

The resulting comment ID, however, is different in each instance. For example, the post which has a comment_id of 15 in the old instance has a comment_id of 59a935ae0718612fce6740b0 on the new instance.

This is a major issue since it results in the Disqus comment threads becoming dissociated from their corresponding posts. I still have access to the old instance, is there any way to transfer the blog content without losing the comment ids?

Technical details:

• Ghost Version: v1.8
• Node Version: v6.11.2
• Browser/OS: Ubuntu 16.04
• Database: SQLite

@triestpa based on how the importer is currently configured, I can see why this would occur. Definitely still a bug, but your issue makes sense 👍

In the meantime though, you can workaround this issue by manually copying the sqlite database file from one server to the other - this should retain the same data without exporting/importing.

@acburdine Thanks for the quick reply! And thanks for the workaround suggestion, copying the sqlite file to the new instance allowed for a successful migration.
