Dear James, 
Thanks for the support. 
Sorry for my ignorance. This is the first time I upgrade to Samba. In addition, both DCs are in production. 

I saw the link you indicated. 
When you say "Make sure to read the release notes for all the versions you are 
Skipping over for changes. " 

Should I pay attention to the settings options that have been changed? 
Or should I also pay attention to the bugs fixed? 

Another question: 
My current version is 4.4.5. Do I need to read the release notes from all versions until the final release? (4.4.6, 4.4.7, 4.4.8 .... 4.6.2) ?? 

Thank you!
