What was the reason of the transition? Was there a security hole of the former seed generation or usage?
I really wonder because I use several seeds to spread my stake. It is quite an effort to change all of them and store them savely. Nevertheless, thanks for your help!

I've got a question before doing the transition of my balance. I just installed the new version (2.4) on my machine and I am going to following this tutorial https://blog.iota.org/new-gui-transition-phase-explained-b536ed80f412
Is it a problem to use the old seed as the new seed? My old seed already meets the requirements of 81 characters with only capital letters and number 9. I am asking because I stored the old seed on several secureplaces and if I choose a new one I need to update each place with the new seed.
Thanks in advance for your help!

Yes, it is required to use a new seed. You must use a new seed.
