Hoping to be useful to our glorious volunteer Gvf who has been hosting wiki.wikimedia.it for free (as in beer and as in freedom) at his own expense for years and who always asked for some help in solving many problems,
In order to do {T268515} it would be optimal to be able to create databases, but in the current server we have not that privilege.
Since we are trying to **support** the epic volunteer who hosts this site since years, and since we do not want to fill Gvf with things to do, a reasonable thing to do is to try to make an initial transfer from that volunteer's server to the Wikimedia Italia's server called `intreccio`, so there are 0% possibilities to create more unwanted workload for him.
The webmaster in charge (`eme`) of basic interventions on the server `intreccio` suggested that server for this migration, since it's CPU load is usually ~0.12.
This migration is absolutely not destructive. When concluded, we can just do a DNS change.
Now we will notify the WMIT tech list by saying not to try to update wiki.wikimedia.it, since we are already doing this elsewhere.
[X] do a first transfer of everything on another server (`wmit-intreccio`)
[X] run `update.php` successfully to 1.35
[X] drop the Lockdown extension and migrate to `$wgWhitelistReadRegexp`
[X] successfully fix of {T306587}
[X] successfully adoption of extension Echo
[X] successfully adoption of extension Thanks
[X] update of WikiEditor
[ ] announce the final migration
[ ] put the legacy wiki in read-only mode
[ ] final database migration from production
[ ] final database upgrade
[ ] DNS change

Proposed `$wgWhitelistReadRegexp`:
```
$wgWhitelistReadRegexp = [
'/^[^:]*$/', // main namespace
'/^Categoria:/', // Category:
'/^Category:/', // Category:
'/^File:/', // File:
'/^Template:/', // Template
'/^Utente:/', // User:
'/^User:/', // User:
'/^Speciale:PagineSpeciali$/',
// THESE CAN BE PROPOSED FOR ANON ABILITATION
// '/^Speciale:Ricerca/'
];
```
