I use tag to track what version each of my customer is currently using. On the local source tree I move the tag of the customer as I update their system. Problem is that remote does not like it. It sees conflict in tg name. It does not recognize the tag as bein moved. How resolve this?
You will need to force push your moved tag.
In SourceTree for Windows you can enable this option in the Tools/Options/Git tab and then select it when pushing.
The 'force with lease' option, while generally safer will not work for forcing tags, so do not select it for pushing moved tags.
