I know how to make backups and to transfer each client account separately, but I am just wondering if it is possible to transfer all customer accounts in WHM at once. You see, if for example I have more than 200 customers (hosting accounts) and wish to switch to another hosting company it will be difficult for me to transfer each account separately, that’s why I am asking this question. Has anyone had reseller account transfer experience? Thanks in advance!

WHM has an account transfer system built into it.

I replied to you on the other forum

However again I would not suggest putting 200 shared accounts under ANY 1 single reseller account.

I don't think anythings going to be successful without shell access. Especially the larger accounts.

Try asking the host to do it

Yeah, it is better to have your host do it. Your host will have better knowledge of it and will do it faster.

Using WHM I think that it is not a problem at all and as someone said you can hope for the help from your web hoster.

Yes WHM has account transfer support built in. It transfers not just files and db, but sets up email account and move the mails, set up the correct permissions on emails and so on. Fast, automated and great option for moving sites.

BUT, it may fail in case the accounts are huge - very large amount of files, emails etc. So be careful and do manual backup and restore if and when required.

Accounts over 250 megabytes should not be transferred without shell access. That's taken straight from the WHM on-screen instructions.

Think it's better to use a VPS having so many accounts on shared hosting. And you have to transfer them not to reseller account but to a VPS. As for the price range, some VPS deals can be even cheaper than reseller plans that many companies offer. I have seen cheap offers, VPS offers from microvps.com. Just my two cents.
