PowerPoint Deck Revamp and Migration

I’ve accumulated 30 plus PowerPoint decks that are packed with text and images, around 1900 slides but every one of them sits in a mish-mash of old styles. I need each slide brought into my master template so everything finally looks consistent—colors, fonts, placements, footers, the lot. if the work is good I have another batch to go straight after.

Here’s what I’m hoping for: open each original .pptx, copy the existing text and images onto the matching layouts in my template, adjust sizing or cropping where things don’t quite fit, and make sure nothing breaks in presenter view. No redesign is required beyond fitting my brand’s predefined layouts; the goal is faithful migration rather than reinvention.

Deliverables
• A separate, fully updated .pptx for every source deck (expect at least seven, possibly a few more).
• All text, images, and speaker notes intact and formatted according to my template.
• Transitions, if any, left as-is unless they conflict with the new layout.

I work in Microsoft 365, so please ensure all files open flawlessly there. If you’ve handled batch deck conversions before, let me know your typical turnaround per file and any best-practice tips you follow to keep fidelity high.
