I've seen the threads on here about transitions to/from sysadmin.

My story is I am a dev (technology is irrelevant), but in learning that technology it required a lot of server infrastructure. In the last few years, I thus had to setup a lot of infrastructure (AD, DNS, SQL etc) to learn said technology.

I've noticed that I've enjoyed doing sysadmin and got quite good at it, and find it even engrossing (e.g. I am amazed by how decievingly complicated AD is, under the hood).

I'm now thinking of moving into IT infrastructure after about 4 years in various dev (.NET) roles. Any advice?

My concern is that I don't have any experience with hardware load balancers and firewalls like F5 etc, which some jobs require. How could I compensate for that?

Also, I'm rubbish with my hands, would this be a factor? (i.e. maintaining physical kit)?

Thanks
