Speaking as an ex-IBMer, even if you reskill they'll still resource action you in favor or someone younger and less well compensated because experience isn't on the list of check boxes they care about.
All the talk about reskilling is just so you stay calm and comfortable while the cows in front of you get a bolt to the head.
Reskilling is useful to help you find an external job more than an internal one in my experience.
