Can we shutdown TREX while production is running?

We have a production KM connected to a TREX.

We have to shutdown the TREX due to the OS maintenance.

Because we think that TREX only works when it's requested to created indexes, we can shutdown the TREX during the

production time without impacting our KM activities if we do not indexes to be created in the same period.

Is that right?

Points guaranteed. Thanks!
