Powershell: Copy a word from a bottom line to a top line

hello. I have several html files in C:\folder1 I want to copy a word/string below in a line above. For example I want to copy `TWO-2` from the second line into the first line, replacing the word `ONE-1`

BEBE ONE-1 NERO

text text

OANA TWO-2 BOGDAN

**MUST BECOME**

BEBE TWO-2 NERO

text text

OANA TWO-2 BOGDAN

can this be done with PowerShell?
