Let's say I have a collection called "collection1" which uses config set

Now, using "upconfig" command, I upload a new configuration called
"config_set_2". How can I make "collection1" use "config_set_2" instead of
"config_set_1"?
I know that if I upload new configuration with the same name "config_set_1"
and reload the collection then it will have new configuration but I want to
keep the old config set, add a new one and make changes so that collection1
starts using new config set.
Is it possible?
There is an action, available in the zkcli script and possibly
elsewhere, called "linkconfig".
It looks like the config can also be changed with the collections API,
using the MODIFYCOLLECTION action.
https://lucene.apache.org/solr/guide/8_2/collection-management.html#modifycollection
To make the change effective after linking to a new config, you'll need
to reload the collection.
Thanks,
