Jira Software data center 8.4.1 version we setup new instance i don't no how to move like no idea about aws
@damoderLet us take this one by one,
You need to know some basics of AWS,
You can find about these online very easily. Once you know this, we can move ahead with installation of Jira Software Data Center using Cloud Formation template provided by Atlassian - https://aws.amazon.com/quickstart/architecture/jira/
If you get stuck at some you can always ping me back. Or you can also connect with Atlassian/Solution partner for help.
PS - Installation part is easier, but configuration and linking all component is bit complicated.
