Migrating from 2.8.6 to 3.3.7 issues

As the title suggests, I am having issues with alot of missing unsigned char such as BYTES and WORD, is there a replacement for these?

Yes. While it was normal in the early 2000''s to use BYTE, WORD, DWORD, as of 10 years ago so so standard practice is to use "int_" or "uint_" for example uint8_t, uint16_t, uint32_t
