+### Converting To New Syntax ###
+
+For existing HTCondor-CE's utilizing the deprecated old job router syntax can do the following steps to convert
+to using the new syntax:
+
+1.  Output the current configuration by running `condor_ce_config_val -summary > summary-file`
+2.  Convert the stored configuration by running `condor_transform_ads -convert:file summary-file`
+3.  Place the output of the previous command into the HTCondor-CE's configuration.
+4.  Tweak new job routes as needed. For assistance please reach out to [[email protected]](mailto:[email protected])
+5.  Set [JOB_ROUTER_USE_DEPRECATED_ROUTER_ENTRIES](https://htcondor.readthedocs.io/en/latest/admin-manual/configuration-macros.html#JOB_ROUTER_USE_DEPRECATED_ROUTER_ENTRIES)=False
+    in the HTCondor-CE's configuration.
+6.  Restart the HTCondor-CE
+
+!!! note "Not Using Custom Job Routes?"
+    Conversion of job router syntax from the deprecated old version to new only needs to occur
+    if custom job routes have been configured.
