The most expensive mistake here is following advice written for beginners: a long course, tutorial projects, then entry-level applications. It discards everything you already have. The faster path uses your current employer, your existing domain knowledge and your network to enter the new area near your current level.
Most people at this stage carry EMIs, dependents and limited runway, so a transition requiring months without income is not a real option. Design the move so income never stops: build evidence while employed, move internally where possible, and make the external switch the last step rather than the first.
Someone who understands how banking settlement, telecom provisioning or retail supply chains actually work, and can now build in the new domain, is worth more than someone holding only the new skill. Pair the domain you are leaving with the one you are entering — that combination is scarcer than either alone.

No. Employers filter on evidence and level, not on birth year. The obstacle is almost always a profile that presents as a beginner when it does not have to.
Likely, and it only becomes a problem if you enter at the wrong level. Positioned correctly you bring experience the team lacks instead of competing on ground they already hold.
Set a checkpoint a few months out and measure inputs, not luck: artefacts built, internal conversations had, referrals activated, interviews reached. If those are all low, fix the plan before changing the target.
Only if the target role genuinely requires the credential. For most technical domain changes, the same months spent building real work inside a paying job produce a stronger resume.
