Cranks and Bottom Brackets

Hi All,
New to the forum and MTB in general but got a question that I can't seem to find the answer to, so hoping you could help me out...
I currently have a Voodoo Hoodoo hardtail which I find is a great bike however, the frame is too big for me and being short and all, I need all the help I can get!
I'm looking at getting a new frame with the correct size but it runs a different bottom bracket.
On my current frame I'm running Suntour XCM 44/30/22T cranks with a Square Taper bottom bracket
On the potential new frame it runs a BSA 68mm bottom bracket
Am I correct in thinking that I would also need a new set of cranks to go with the frame?
Or is there a way that I can retain the current cranks to use with the different bottom bracket?
After a little reading it looked as though my current frame's bottom bracket also houses the crank spindle too.
Thanks for your help.

Measure your current BB shell - 99% chance it will be the same. BSA is just the standard British thread which all mountain bikes use unless it's press fit. 68mm is very common unless it is 73mm which is unlikely.I don't do smileys.

To add, BSA 68mm is the bottom bracket shell in the frame, the default fitment inside that until about 10 years ago (and still lost common) is a square taper bottom bracket.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

Off the top of my head the Voodoo mtbs run a 73mm bb
see section 2 for measuring

The last voodoo I had was 68mm, why would it be 73?Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

Pretty sure I had to order the last couple I replaced as we only keep 68mm in store0

Thanks for the replies and advice!
I think best port of call would be too just whip to crank off and do a bit of investigating instead of being lazy :P0 -
Easy enough to measure the BB shell - don't even need to take anything off.I don't do smileys.
