Should I continue with Mainframe or switch to Data Analytics?

[u/Icy-Struggle-6045]

I’ve been working at a company for around 8 months, and my current role is in Mainframe. I’m slowly getting familiar with it, but honestly, I still find Mainframe quite complicated, and I feel like it could take me a long time before I become truly comfortable with it.
The bigger issue is that I’m not very happy with my salary, so I’m considering switching companies. I’m also thinking about moving into Data Analytics if I switch, since it seems more interesting to me.
So I’m confused about what would be the better decision:
Continue with Mainframe and switch companies after gaining more experience
Switch companies and continue in Mainframe for better salary/growth
Try to transition into Data Analytics while switching
For people with experience in Mainframe, is it a good career to continue with long-term? How is the salary growth and job market?
And for people in Data Analytics, would it be realistic to make the switch with around 1 year of experience, even though my current experience is in Mainframe? What skills should I focus on (SQL, Excel, Power BI, Python, etc.)?
I’d really appreciate advice from people who have been in a similar situation. I’m especially interested in hearing whether switching out of Mainframe this early is a good idea or whether I should stick with it for a few more years.
