Copy Jenkins to another instance

Hi,

I have Jenkins jobs in instance A and need to copy jobs to instance B, I tried “import job” option. But I don’t have admin credential of instance A.

Is there any way to copy jobs from one to another

as long as you have configure permissions on the jobs from instance A you don’t need admin credentials there.
You can get the config.xml of the jobs (<jenkinsA>/job/myjob/config.xml) and POST that xml to instance B to
<jenkinsB>/createItem?name=myjob
See <jenkinsB>/api
You will need to make sure that all plugins used by the jobs you want to copy are also installed on the new instance. Also any used credentials need to exist with the same id.
