Description

Hello Wei,

Per our document https://documentation.suse.com/sles/15-SP1/pdf/book-security_color_en.pdf

When upgrading from SUSE Linux Enterprise 12.x to SUSE Linux Enterprise 15 SP1, SuSEfirewall2 is not changed and remains active. There is no automatic migration, so you must migrate to firewalld manually. firewalld includes a helper migration script, susefirewall2-tofirewalld . Depending on the complexity of your SuSEfirewall2 configuration the script may perform a perfect migration, or it may fail. Most likely it will partially succeed and you will have to review your new firewalld configuration and make adjustments. The resulting configuration will make firewalld behave somewhat like SuSEfirewall2. To take full advantage of firewalld 's features you may elect to create a new configuration, rather than trying to migrate your old configuration. It is safe to run the susefirewall2-to-firewalld script with no options, as it makes no permanent changes to your system. However, if you are administering the system remotely you could get locked out.

root # zypper in susefirewall2-to-firewalld
root # susefirewall2-to-firewall


I am not sure if the migration tests cover this test scenario, can you please double check on this? and let me know if any questions.

BR//Richard.
