Delete outdated custom framework?

[Nelson Fredsell (nelsonf)]

Hello everyone,

I'd like to delete an outdated MARC framework that I no longer use, but receive a warning that a number of records are related.  If I delete the old framework, how will it impact the existing attached biblio records that were catalogued?   Using Koha Linux 3.0, but soon updating to 3.4.

I tested by creating a new framework "tmp" using an existing custom pared-down framework with minimal number of MARC tags, and then created a test biblio record and associated item.  When I went to delete "tmp" framework, the warning I received was "This framework is used 28 times." when actually I had only used it 1 time. I deleted the framework, then searched for the biblio and could not find it!  I sure hope that 28 (or 27) legitimate records weren't deleted, but I don't know how to determine which records are associated with which frameworks.

Is the moral of the story, "Never delete frameworks that have biblio records attached"?

Thanks very much,
Nelson
