Space saga book series where the wealthy can afford to transfer their minds into younger bodies grown from their DNA

Question

This book series was I believe at least three books long. I started reading it 10+ years ago. This was hard science fiction not fantasy.

It starts with a murder of a wealthy person. The wealthy can afford to transfer their mind into a new body grown from their DNA when they get old. I think the memories of the person murdered were either stolen or destroyed so an investigation was started. There are human colonies on many planets.

There were a ton of characters in these books. The narrator changes many times as there are many storylines woven throughout this universe. Not Dune or Children of Time.

Answer 1

This sounds a lot like the Commonwealth Saga by Peter F Hamilton.

The first book is called Pandora's Star (2004), and certainly fits the description of there being a LOT of characters, and a murder where someone's "backup" memories are lost.

The year is 2380. The Intersolar Commonwealth, a sphere of stars some four hundred light-years in diameter, contains more than six hundred worlds, interconnected by a web of transport "tunnels" known as wormholes. At the farthest edge of the Commonwealth, astronomer Dudley Bose observes the impossible: Over one thousand light-years away, a star... vanishes. It does not go supernova. It does not collapse into a black hole. It simply disappears. Since the location is too distant to reach by wormhole, a faster-than-light starship, the Second Chance, is dispatched to learn what has occurred and whether it represents a threat. In command is Wilson Kime, a five-time rejuvenated ex-NASA pilot whose glory days are centuries behind him.

Opposed to the mission are the Guardians of Selfhood, a cult that believes the human race is being manipulated by an alien entity they call the Starflyer. Bradley Johansson, leader of the Guardians, warns of sabotage, fearing the Starflyer means to use the starship's mission for its own ends.

Pursued by a Commonwealth special agent convinced the Guardians are crazy but dangerous, Johansson flees. But the danger is not averted. Aboard the Second Chance, Kime wonders if his crew has been infiltrated. Soon enough, he will have other worries. A thousand light-years away, something truly incredible is waiting: a deadly discovery whose unleashing will threaten to destroy the Commonwealth... and humanity itself. Could it be that Johansson was right?

This could also be Richard Morgan's Takeshi Kovacs series, in particular the first book, Altered Carbon.

From Wiki:

In the future, humans have achieved virtual immortality. Most people have cortical stacks in their spinal columns that store their consciousness. If their body dies, their stack can be stored indefinitely. [...]

While most people can afford to get resleeved at the end of their lives, they are unable to update their bodies and most go through the full aging process each time, which discourages most from resleeving more than once or twice. Thus, while people can live indefinitely in theory, most choose not to. Only the wealthy are able to acquire replacement bodies on a continual basis. Those who have lived for multiple lifespans are called Meths, a reference to the Biblical figure Methuselah. The very rich are also able to keep copies of their minds in remote storage, which they update regularly. This ensures that even if their stack is destroyed, they can be re-sleeved. [...]

On Earth, a Meth named Laurens Bancroft has died in mysterious circumstances in Bay City (formerly San Francisco). The re-sleeved Bancroft has no memories of the previous two days, including his own death. Though police officer Kristin Ortega believes he committed suicide, Bancroft is convinced he was murdered
