Hi,
If your THREDDS instance went from 4.6 to 5.x then you are probably running
into the same thing I did that is detailed in the following GitHub issue:

Subject: [thredds] Uncorrelate disk path and href for catalogRef and dataset in
catalog.xml
Hello everyone,
I'm migrating Thredds instances, and as I do so, I'm also reorganising Thredds
folders.
We have a large amount of catalogRef and datasets that are located under
{tds.content.root.path}. I would like to move them all to a new folder
{tds.content.root.path}/catalogs to simplify management.
However doing so, an extra /catalogs/ is added to the URL of each of the
underlying datasets.
ex :
https://tds0.ifremer.fr/thredds/CERSAT.html =>
https://tds0.ifremer.fr/thredds/catalogs/CERSAT.html
My root catalog is the following :
<?xml version="1.0" encoding="UTF-8"?>
<catalog name="tds0"
xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0";<http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0>
xmlns:xlink="http://www.w3.org/1999/xlink";<http://www.w3.org/1999/xlink>>
<catalogRef xlink:title="CERSAT" xlink:href="catalogs/CERSAT.xml" name=""/>
<catalogRef xlink:title="CORIOLIS" xlink:href="catalogs/CORIOLIS.xml" name=""/>
<catalogRef xlink:title="LPO" xlink:href="catalogs/LPO.xml" name=""/>
</catalog>
I tried several solution but none of them worked :
- adding in threddsConfig.xml a catalogRoot element pointing to a new
catalog.xml file located at catalogs/catalog.xml. But it resolves as url :
thredds/catalogs/catalog.html
- using attributes name, ID, alias, urlPath in the definition of catalogRef
elements in catalog.xml file trying to truncate catalogs/ folder
- defining default catalog.xml at startup, but couldn't find a java parameter
to do so. Only tds.content.root.path is settable.
It is quite important to keep the same urls while migrating as a lot of
products stored in the Ifremer Thredds instances are referenced in multiple
services with their urls.
Maybe I missed a configuration while reading the docs. Does anybody know if
it's possible and how to do it ?
Thanks,
