There is no easy and safe way to do it. I have 14 added toolbars with 207 macros call outs by the toolbars. I figured out how to hack the registry file to add macros and the toolbars for new versions. It is not recommended to do this. There is my idea request to implement the capability. Vote for idea here:Implement migration of customized menus, toolbar and Macros Command Files list. - D15325
Is your hacking procedure of the registry file available ?
I also use few Custom toolbars with many macros...
I ended my hacking carreer when I was young !
I was hoping for a simpler procedure since we all have customizations!
