Is it worth bothering and transferring page urls when moving from Joomla to Bitrix or will 301 redirects be enough?

Question

Joomla

Friends!
I understand that the issue has been raised many times, but we need the most up-to-date information, preferably real experience.
We plan to move from Joomla to Bitrix in the near future.
Is it worth bothering and transferring page urls (this is not a trivial task given our addressing) or will 301 redirects be enough?
What to do with links in SAPA - remove them and gradually replace them with new addresses or leave them as they are?
Shall we sit down by positions?
I will be grateful for the answer.

Answer 1

Of course, it's best to save the addresses, but if it's very time consuming, then make a 301 redirect and don't worry, everything will be fine. this is a normal solution.
and links should be removed.

Answer 2

We moved the site https://kaport.ru with full preservation of links. We did not observe any failure in the issuance, the new site was indexed in 3-4 days, we were very pleased with the result. Previously, there were mostly not very good experiences in terms of url changes, relocations.
