Greene King will sell 20 of the 136-strong Old English Inns pubs it bought in September - the rest will be integrated into the estate.
But Old English Inns will not lose its identity.
Following the takeover by Suffolk-based brewer and pub operator, 82 of the acquired pubs will remain as managed houses to form a new division within Greene King under the current Old English brand.
The remaining 34 will be converted to tenanted pubs and integrated into Greene King's Pub partners operation.
The decision follows an extensive review of the business and consultation with Old English staff over the past month. It also recently spent £200,000 on a conference in Birmingham to introduce the Greene King management to its new staff.
"Old English is already a well established name with a large constituency of loyal customers," said managing director Neil Gillis.
"Following our assessment of Old English houses we are delighted with the outstanding quality of management and the operation of businesses throughout the estate."
