twiki to confluence migration

Question

I am just trying to do a trial of twiki to confluence migration using UWC.

UserList is first page to migration from Twiki, but it fails with UWC log saying

The converted page is uploaded to confluence, but not correctly.

Since this had been tried by many time in past by other. So I would appreciate if anyone can guide me  to solve this issue.

It has been deprecated for some time, so would have to be an early version 5.x release (certainly before they changed the database).

The easiest thing to do is spin up an early 5.x installation and see if it works. The official possition is that support ended at 4.3.7

This post seems to indicate it worked with 5.5.7

I know when my team did a conversion for a client, it did involve a fair amount of work to get it working reliably.

It is correct that UWC is deprecated, But I think must have been working to migrate the twiki content to confluence 5.x

If I remember correctly, the UWC is deprecated, due to many changes in the Confluence database/API. It is not an out of the box solution, but more of starting point to mod/update to the current API.
