Rules based VirtualTV channels not working (referencing old JSON files after migration to another NAS)

[s1mwest 2]

Hey, I'm doing a test run of migrating Emby server from one NAS to another, but I've run into an issue that's only affecting creating rule-based channels in VirtualTV on the target server. Can anyone give me an idea if I can fix this, and provide any pointers if so? Thank you.

Migration has generally been ok but VirtualTV plugin on the target NAS fails to include any videos for rule based channels that I create. Playlist based and Collection based channels work fine. From what I have seen in logs, something keeps referring to old JSON files (eg Could not find file ... VirtualTV-07332953b2e5403fb61268cc17caacc8.json), which I believe did not come across in the migration, I guess. But I'm confused as to what is remembering the reference to these files after I've performed a cleanup, or how to clear it. This seems to be the blocker for me.

I've attempted various steps such as uninstalling VirtualTV, using SSH to delete it's cache and checking [MediaItems] table via SQL to ensure previous channels aren't remaining. I clear what I can find but somehow the old JSON file is still being referenced and therefore creating new rules based channels fails because of this. Well, I say fail, but I mean that the channel is created, but no videos are included when i refresh or force refresh guide data.  The criteria & channel settings are same as what was used on the source server.

I'd really like to keep the config that I imported, so any help is appreciated.

DSM 7.3.2 Update 3 Emby server v4.10.0.11 - VIrtualTV v2.1.7.0

Migration steps:

Source server

1. Export emby config

Target server

2. Import emby config

3. Update folder location for each library on new server & check local system user 'emby' has read/write access

4. Scan libraries

5. Refresh Metadata for all libraries

6. Install VirtualTV plugin on target server (Should this have been installed before import?)

7. Create Collection based and Playlist based channels -> Refresh Guide = ok

8. Create Rules based channel -> Refresh gude = no files are included "Returning 0 TVShows Items" shows in log

9. Then mutiple failed attempts to rememdy, as described above
