Just retain your SOLR_HOME folder with all your data and point your new install to the same. If SolrCloud, point to the same Zookeeper.
Assuming you installed a standalone single node Solr with the Linux installation script, then your solr unpack wil be in /opt/solr-8.11.1, with a symbolic link from /opt/solr, and your data will be at /var/solr/data. You can then run the installation script for 8.11.2 with the -f option, which will install 8.11.2 in /opt/solr-8.11.2 and change the symbolic link to point to the new install. Your data will be left unchanged, and a stop/start is all you need. Detailed instructions in for the install script in https://solr.apache.org/guide/solr/latest/deployment-guide/taking-solr-to-production.html#service-installation-script <https://solr.apache.org/guide/solr/latest/deployment-guide/taking-solr-to-production.html#service-installation-script> and for the upgrade process in https://solr.apache.org/guide/solr/latest/deployment-guide/upgrading-a-solr-cluster.html <https://solr.apache.org/guide/solr/latest/deployment-guide/upgrading-a-solr-cluster.html> If you have installed in some other way, follow the same principle of retaining your SOLR_HOME. If you have a Cloud cluster, upgrade one node at a time.
