How to transfer?

I’m a public senior high school teacher assigned in the province but living in the city. Fortunately, 1-hour ride lang naman ang biyahe but hassle pa rin especially now that I’m with a toddler. I’m planning to transfer sa city division namin but don’t know the process. I’m planning na magpa rank nalang uli but honestly nakakadrain na parang back to square one na naman sa pangalkal ng documents.

Also, I’m bothered na if magcontinue ako magparank is possible na balik T-I ako when I’m already in T-II. Concerning din na mag oopen na soon yung promotion for T-III to T-7 for SHS teachers so may doubts din ako if magtatransfer kase baka mahirapan ako mapromote.

Any advice po? Thank you so much.
