   - Setting csmacdSupport=false for Ethernet MACs.
   - Etc.
 
-The necessary changes are available in the following branches:
+For re-running the fingerprint tests, use the following versions/branches:
 
-1. `topic/bz/inet3_to_inet4_migration` – this would be the release prepared for INET4
-2. `topic/bz/inet4version_for_migration_test` – this is where the fingerprints match the best:
-    Nagle's algorithm disabled for TCP, modified cable lengths, etc.
-3. `v20250602` – modified OpenFlow for INET3: some fixes and bug corrections
-4. `topic/bz/inet3version_for_migration_test` – this is where the fingerprints match the best:
-    Nagle's algorithm disabled for TCP, modified cable lengths, etc.
+In OpenFlow (these changes disable Nagle's algorithm, modify cable lengths, etc.):
 
-Branches 2 and 4 are only needed for testing and can be deleted in the long term.
+1. `topic/bz/inet4version_for_migration_test` – modifies migrated version (INET 4.x)
+2. `topic/bz/inet3version_for_migration_test` – modifies `v20250602`  (INET 3.x)
 
-In INET:
+Apply the following patches to INET. They reduce the differences between INET 3.x and 4.x
+versions so that identical fingerprints can be achieved:
 
-1. `topic/bz/for_openflow_test` – prepared for testing OpenFlow with INET4, TCP was modified to behave as similarly as possible to how it works in INET3.
-    These changes also availables in inet4patch_for_openflow_migration_test.patch file for inet v4.5.0 release.
-2. `topic/bz/v3.x_for_openflow_test` – prepared for testing OpenFlow with INET3, with Nagle’s algorithm disabled in TCP.
-    These changes also availables in inet3patch_for_openflow_migration_test.patch file for inet v3.8.5 release.

-These INET branches were only needed for testing and can be deleted in the long term.
+1. `inet3patch_for_openflow_migration_test.patch`: patch for inet-3.8.5
+2. `inet4patch_for_openflow_migration_test.patch`: patch for inet-4.5.4
