401k conversion to IRA

I was looking to rollover a 401k with a former employer into my current employers 401k. It turn out it’s a bit onerous due to extra documentation my current employer requires. Rolling it over into an IRA with my main brokerage firm is much simpler.

My main concern is I do a backdoor Roth IRA every year and from my understanding it can create problems/complexities with this process in future years if I now have a traditional IRA balance.
