I have noticed that no usergroups were included in the lists.
If I add any of site's user groups or combination, I'm getting this error in
frontend accessing this list:

0 - PHP regular expression limit reached (pcre.backtrack_limit)

Edit your Userlist and ensure groups have been selected to be included in the list. Next check your filters, sorting, and columns tabs to ensure everything is configured as expected. The migration seams to have went a little wonky for you (unsure why, migration seams to work ok in my tests).

I have noticed that no usergroups were included in the lists.
If I add any of site's user groups or combination, I'm getting this error in

0 - PHP regular expression limit reached (pcre.backtrack_limit)

Never seen such an error. You'll likely need to adjust PHP.ini and increase pcre.backtrack_limit and pcre.recursion_limit. Contact your host if unsure how.

I have dedicated non-virtual server with default Ubuntu 14.04 apache|php settings, which were:

pcre.backtrack_limit 1000000 1000000
pcre.recursion_limit 100000 100000

I had increased both numbers by factor 10, now the CB list page is loaded without errors, but it took unreasonable amount of time to generate it:

No such problems with any other pages, including CB profile

And generated user list looks very strange:
- looks like it has all (916) user entries on the first page, switching to second page renders no user entries
- there is paginations links, but its number corresponds to number of users (916), not number of users devided by _users_per_page_ parameter
