You can export the current filter profile as xml. Modify the xml with the correct drive letter and import it back. The details are in Analytics User's Guide.
I have gone through the doc that explains how to export hosts/ group but not profiles -filter. There is only import tab under filter. Could you please provide additional info.
My mistake on the legacy product. Export filter profile feature was never implemented.
You need to create the xml file and import into Analytics. There is an example in Analytics Users Guide, XML for importing Filter Profiles section.
Another option is to update Analytics backend database. This is not supported but it can be done if you have DBA assistance. The two tables are S3_FILTER_PROFILE and S3_FILTER_PROFILE_ITEM. You need to obtain S3_FILTER_PROFILE.FILTER_PROFILE_ID for the matching name for filter profile (e.g. SELECT FILTER_PROFILE_ID, NAME FROM SOLIDCOR.S3_FILTER_PROFILE WHERE NAME = "<FILTER_NAME>;). You can update the value in S3_FILTER_PROFILE_ITEM that matches FILTER_PROFILE_ID.
This should be done by DBA. Make sure a table backup is performed prior to any update with Analytics Server Service stopped.
Updating the SQL tables as per your instructions fixed it..
